One can then apply various features of the lesions to this differential, and exclude some things, elevate some things, and downgrade others in the differential. NOF, fibrous dysplasia, multifocal osteomyelitis, enchondromas, osteochondoma, leukemia and metastatic Ewing' s sarcoma. Aggressive periosteal reaction Growth has been demonstrated well after skeletal maturity. This image is of a 20 year old patient with a sclerotic expansile lesion in the clavicle. Bone reacts to its environment in two ways either by removing some of itself or by creating more of itself. These tumors may be accompanied by a large soft tissue mass while there is almost no visible bone destruction. Location within the skeleton Most commonly encountered bone tumor in the small bones of the hand and foot. Generally, this just follows common sense some lesions should logically be expected to be focal, others multifocal, and yet others diffuse or systemic. Patients usually have sclerotic bone lesions before and lytic bone lesions after puberty. (A) Small radiolucent lesion exhibiting a thin sclerotic border (arrow) is present in the lateral cortex of the distal tibia of a 13-year-old boy. Multiple enchondromas are seen in Morbus Ollier. You may have been surprised to see metastatic disease listed as a leading cause for diffuse sclerotic bones. These lesions are not osteochondromas, but consist of reactive cartilage metaplasia. Chordoma is usually seen in the spine and base of the skull. Differentiation of Predominantly Osteoblastic and Osteolytic Spine Metastases by Using Susceptibility-Weighted MRI. Radiology. Lets apply the good old universal differential diagnosis to sclerotic bone lesions. Rib lesions detected on bone scintigraphy often require further characterization with radiography or CT to improve specificity (Figs. Because of the large dimensions with soft tissue extension on plain radiograph and axial T2-weighted MR image, a high grade chondrosarcoma was suspected. In the subchondral bone, the number of TRAP-positive cells peaked on day 14. This is an example of progression of an osteochondroma to a peripheral chondrosarcoma. The lesson here is that when we are dealing with a very common disorder, even its less common presentations will be seen commonly. Case 7: metastases from prostate carcinoma, Sclerotic bone pseudolesions - external artifact, bizarre parosteal osteochondromatous proliferation (Nora lesion), conventional intramedullary chondrosarcoma, dysplasia epiphysealis hemimelica (Trevor disease), solitary bone plasmacytoma with minimal bone marrow involvement, mixed lytic and sclerotic bone metastases, Lodwick classification of lytic bone lesions, Modified Lodwick-Madewell classification of lytic bone lesions. The mean and maximum attenuation were measured in Hounsfield units. The evaluation of a solitary bony lesion in the spine may be more challenging and will often require additional diagnostic testing if benign imaging features are not present on MRI. Halo of increased signal on T2 W images about the low signal central lesion is suggestive of metastatic disease. Materials and Methods 1. Here a chondrosarcoma of the left iliac bone. Contrast-enhanced T1-weighted MR image demonstrates heterogeneous enhancement of the mass with extensive surrounding edema.

Typical presentation: well-defined osteolytic lesion in tarsal bone, patella or epiphysis of a long bone in a 20-year old with pain and swelling in a joint. Uncommonly it can be difficult to differentiate a stress fracture from a bone tumor like an osteoid osteoma or from a pathologic fracture, that occurs at the site of a bone tumor. Isaac A, Dalili D, Dalili D, Weber M. State-Of-The-Art Imaging for Diagnosis of Metastatic Bone Disease. Osteoblastic Metastatic Lesions. A lumbar puncture (LP) is a diagnostic procedure used to obtain a sample of cerebrospinal fluid (CSF) to look for signs of infection or inflammation. Finally other clues need to be considered, such as a lesion's localization within the skeleton and within the bone, any periosteal reaction, cortical destruction, matrix calcifications, etc. sclerosing osteomyelitis of Garr, aggressive features might require an oncological referral and/or biopsy 1, history of malignancy will almost always require additional imaging, follow-up or oncologic referral, high CT attenuation values might help in the differentiation of bone island from osteoblastic metastases 5 but attenuation values should not be used exclusively for the assessment of sclerotic bone lesions 6, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Here a patient with a broad-based osteochondroma with extension of the cortical bone into the stalk of the lesion. Focal sclerotic bony lesions (mnemonic). Typical bone metastases are osteolytic (87.5%), with medullary origin (91.6%), and they cannot be distinguished from other osteolytic metastases on the basis of imaging criteria alone. DD: juxtacortical chondrosarcoma, parosteal osteosarcoma. Spinal lesions are commonly spotted on imaging tests. Multiple myeloma is a hematologic malignancy of plasma cells that causes bone-destructive lesions and associated skeletal-related events (SREs). MRI features high sensitivity and high specificity for the demonstration of bone metastases in general and for assessing the bone marrow 2,3. Osteoblastic metastases have a lower fracture risk than lytic or mixed bone metastases 11-13. post-treatment appearance of any lytic bone metastasis. Osteopetrosis and pyknodysostosis are likewise hard to mistake for other entities since the bones are denser than in any other disorder, and the long bones tend to have very tiny medullary canals. Likewise patients with sclerotic lesions due to various drugs or minerals will tell you what they are taking if you ask them. The most common appearance is the mixed lytic-sclerotic. Ossifications or calcifications can be present in variable amounts. Differential Diagnosis in Orthopaedic Oncology. PET features high sensitivity in the detection of bone metastases especially 18 NaF-PET is suitable for the detection of sclerotic metastases since it shows tracer uptake in locations with osteoblastic activity and is more accurate than FDG-PET 3. The differential diagnosis of bone lesions that result in bony sclerosis will be given. Click here for more examples of eosinophilic granuloma. <-Lucent Lesions of Bone | Periosteal Reaction->. In this paper, we review the recent years of literature on deep learning-based multiple-lesion recognition. Well, generally, it means that it is due to a fairly slow-growing process. Society of Skeletal Radiology- White Paper. Non-ossifying fibroma which has been filled in. However, cancers that metastasize to bone are very common. When considering congenital causes of sclerotic lesions, benign causes such as bone islands or osteopoikilosis usually have a fairly typical appearance and are hard to mistake. Contact Information and Hours. some benign entities in this region may mimic malignancy if analyzed using classical bone-tumor criteria, and proper patient management requires being familiar with these presentations. 4. Interventional Radiology). Osteoblastic metastatic disease (see Table 33.1): More often multiple with increased uptake on bone scan. The cortical bone and bone marrow compartment are not involved. 2019;290(1):146-54. A 30-year-old woman underwent a CT of the pelvis for endometriosis and an incidental lesion was found in the sacrum. Metastases and multiple myelomaIn patients > 40 years metastases and multiple myeloma are the most common bone tumors.Metastases under the age of 40 are extremely rare, unless a patient is known to have a primary malignancy.Metastases could be included in the differential diagnosis if a younger patient is known to have a malignancy, such as neuroblastoma, rhabdomyosarcoma or retinoblastoma. We provide care in several areas of orthopedics, such as: hand and wrist care, foot and ankle care, and joint replacement. Frequently encountered as a coincidental finding and can be found in any bone. 6. ADVERTISEMENT: Supporters see fewer/no ads. Osteomyelitis is a mimicker of various benign and malignant bone tumors and reactive processes that may be accompanied by reactive sclerosis. However, if one sees sinus tracts associated with a sclerotic area, one should strongly consider osteomyelitis. AJR 2000; 175:261-263. Amsterdam: Elsevier; 1993. 4. In the cases in which the solitary sclerotic lesion has increased, uptake on bone scan, follow-up CT, or plain film imaging is recommended at 3-, 6-, and 12-month intervals. Plain radiograph and coronal T1-weighted contrast-enhanced fat-suppressed MR image of a mixed lytic and sclerotic lesion of the distal femoral diaphysis. 1988;17(2):101-5. Metastases are the most common malignant bone tumors. Systematic Approach of Sclerotic Bone Lesions Basis on Imaging Findings. A popular mnemonic to help remember causes of focal sclerotic bony lesions is: Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. This is consistent with the diagnosis of a reactive process like myositis ossificans. T2-weighted MR image reveals a lobulated mass with high signal intensity. Matching the degradation rate of the materials with neo bone formation remains a challenge for bone-repairing materials. Check for errors and try again. 2020;60(Suppl 1):1-16. A juxtacortical chondrosarcoma has be considered in the differential diagnosis when a mineralized lesion adjacent to the cortical bone is seen. . 105-118. The signal intensity on MR depends on the amount of calcifications and ossifications and fibrous tissue (low SI) and cystic components (high SI on T2). Fundamentals of diagnostic radiology. Edema often present in the surrounding bone marrow. Bone metastases are the most common malignancy of bone of which sclerotic bone metastases are less common than lytic bone metastases. About Us; Staff; Camps; Scuba. Cancers (Basel). Adam Greenspan, Gernot Jundt, Wolfgang Remagen. Parosteal osteosarcoma is a sarcoma that has it's origin on the surface of the bone. Bone islands can be large at presentation. 2021;50(5):847-69. Sclerotic means that the lesions are slow-growing changes to your bone that happen very gradually over time. Notice the lytic peripheral part with subtle calcifications. Most of the time, sclerotic lesions are benign. 2019;15:100205. Diffuse bony sclerosis (mnemonic) Last revised by Joshua Yap on 28 Jun 2022 Edit article Citation, DOI & article data A mnemonic for remembering the causes of diffuse bony sclerosis is: 3 M's PROOF Mnemonic 3 M's PROOF M: malignancy metastases ( osteoblastic metastases) lymphoma leukemia M: myelofibrosis M: mastocytosis S: sickle cell disease brae in keeping with diffuse bone infarcts. Radiographs are specific but suffer from low sensitivity 1. Symptoms include pain, abnormal sensations, loss of motor skills or coordination, or the loss of certain bodily functions. Here a lesion located in the epi- and metaphysis of the proximal humerus. If the osteonecrosis is located in the epiphysis, the term avascular osteonecrosis is used. Macedo F, Ladeira K, Pinho F et al. The zone of transition is the most reliable indicator in determining whether an osteolytic lesion is benign or malignant (1). Cortical destruction (3) Here an example of a patient with a stress fracture of the distal fibula. Solitary lucent lesions in bone with a distinct margin are generally called "geographic" lesions, whether or not they have a sclerotic rim. The bone marrow compartment is not involved which is important for the surgical strategy. The sagittal T1WI and Gd-enhanced T1W-image with fatsat show a large tumor mass infiltrating a large portion of the distal femur and extending through the cortex into the soft tissues. For those that are possibly cancerous, a biopsy is conducted to identify it. A Novel Classification System for Spinal Instability in Neoplastic Disease: An Evidence-Based Approach and Expert Consensus from the Spine Oncology Study Group. Conclusion. Here a lesion in the epiphysis, which was the result of post-traumatic osteonecrosis. The contour of the involved bone is usually normal or with mild expansive remodelling. 3. Publicationdate 2010-04-10 / update 2022-03-17. Gadolinium is usually minimal or absent (see right image). 20 yo M w/ 5 cm lytic bone lesion in proximal tibia metaphysis, sharply demarcated w/ sclerotic rim. 2022;51(9):1743-64. Sarcoidosis is a multi-system disease with a range of . 1991;167(9):549-52. Azar A, Garner H, Rhodes N, Yarlagadda B, Wessell D. CT Attenuation Values Do Not Reliably Distinguish Benign Sclerotic Lesions From Osteoblastic Metastases in Patients Undergoing Bone Biopsy. Wide zone of transition Confavreux C, Follet H, Mitton D, Pialat J, Clzardin P. Fracture Risk Evaluation of Bone Metastases: A Burning Issue. Guidelines for the Diagnostic Management of Incidental Solitary Bone Lesions on CT and MRI in Adults: Bone Reporting and Data System (Bone-RADS). 1989. Common: Metastases, multiple myeloma, multiple enchondromas. If the disorder it is reacting to is rapidly progressive, there may only be time for retreat (defense). Sclerotic bone lesions are rare; commonly affects the axial skeleton (pelvis, spine, skull, ribs) and the patients are often symptomatic as opposed to the patients with lytic lesions who rarely have any symptoms. Studies suggest that beyond joint wear and tear . Fibro-osseous lesion like fibrous dysplasia. A benign type of periosteal reaction is a thick, wavy and uniform callus formation resulting from chronic irritation. The diagnosis was fibrous dysplasia. Imaging of skull vault tumors in adults: Author: Pons Escoda, Albert Naval Baudin, Pablo . Development in centrally located osteochondromas like the pelvis, hip and shoulder is most common. Resonance Imaging Saeed M. Bafaraj . Bone Metastases: An Overview. Bone scan shows no high activity, opposed to low-grade intraosseous osteosarcoma. Osteoid matrix Other benign lesions, like solitary bone cyst, fibrous dysplasia, chondroblastoma and other benign bone tumors may become inert and may also become sclerotic. Mark Blumenkehl, MD is a specialist in Gastroenterology whose practice locations include: Detroit, Sterling Hgts Fundamentals of Skeletal Radiology, second edition 13. After an injury, different types of fluid can build up in a bone. Degenerative subchondral cyst: epiphyseal, Chondroid matrix in cartilaginous tumors like enchondromas and chondrosarcomsa. Sclerosis is present from either tumor new bone formation or reactive sclerosis. Growth of the osteochondroma takes place in the cap, corresponding with normal enchondral growth at the growth plates. Causes include trauma, infection, autoimmune diseases, inflammatory diseases, spinal degeneration, congenital malformations, and benign or cancerous tumors. Clinically relevant bone metastases are a major cause of morbidity and mortality for prostate cancer patients. However, a specific density range has not been specified for those terms 1. A brain MRI can . Case Report Med. Most commonly originate from prostate and breast cancer and less frequently from lung cancer, lymphoma or carcinoid. Mineralization in osteoid tumors can be described as a trabecular ossification pattern in benign bone-forming lesions and as a cloud-like or ill-defined amorphous pattern in osteosarcomas.

In this article we will discuss the differential diagnosis of sclerotic bone tumors and tumor-like lesions in more detail. The illustration on the left shows the preferred locations of the most common bone tumors. Age: most commonly seen in 10-25 years, but may occur in older patients. and PD-L1 PET/CT (PD-L1 positivity is defined as having at least one lesion with radiotracer uptake over the . 2018;2018:1-5. ImageBenign periosteal reaction in an osteoid osteoma.Large arrow indicates solid periosteal reaction.Small arrow indicates nidus. Journal of Bone Oncology. Amorphous mineralisation is present in most lesions. 2021;216(4):1022-30. by Mulder JD, et al. Mixed lytic and sclerotic bone metastases are characterized by the presence of both components, that is areas of bone destruction and areas of increased bone formation within one metastatic tumor deposit or one primary tumor that features both kinds of bone metastases, namely osteolytic and osteoblastic metastases 1. 1 When the vertebral lesion has no benign features, especially in the older adult patient, metastatic disease is always a significant consideration. Many sclerotic lesions in patients > 20 years are healed, previously osteolytic lesions which have ossified, such as: NOF, EG, SBC, ABC and chondroblastoma. (B) In another patient, a 21-year-old woman, note a radiolucent lesion with sclerotic border affecting the medial cortex of the distal femur ( arrows ). 3, Increased uptake on bone scan associated with a solitary sclerotic lesion is atypical and therefore more worrisome, but largely unhelpful as there are many reports of bone islands having increased Tc-99 m hydroxydiphosphonate (HDP) uptake. Here an incidental finding of several eccentric sclerotic lesions of the distal femur. Bone marrow edema can happen with fractures and other serious bone or joint injuries. . AJR Am J Roentgenol. Disappearane of calcifications in a pre-existing enchondroma should raise the suspicion of malignant transformation. For example: Differential Diagnosis of Focal or Multifocal Sclerotic Bone Lesions. This 'neocortex' can be smooth and uninterrupted, but may also be focally interrupted in more aggressive lesions like GCT. An aggressive type is seen in malignant tumors, but also in benign lesions with aggressive behavior, such as infections and eosinophilic granuloma. WSI digital slide: https://kikoxp.com/posts/4606. The cause of sclerotic lesions was assessed histologically or by clinical and imaging follow-up. 2018;10(6):156. Prevalence of 3-5% in patients with hereditary multiple osteohondromas. Therefore, knowing the homogeneously sclerotic bone lesions can be useful, such as enostosis (bone island) (), osteoma (), and callus or bone graft.The plain radiography and CT images of enostosis consist of a circular or oblong area of dense bone with an irregular and speculated margin, which have been . The differential diagnosis of bone lesions that result in bony sclerosis will be given. The image on the right is of a different patient who has an old NOF that shows complete fill in. 2. Diffuse skeletal infarcts can be a common cause of diffuse skeletal sclerosis. If there are multiple or polyostotic lesions, the differential diagnosis must be adjusted. Unable to process the form. mutation, and both sclerotic and lytic bone lesions together for the first time. 7. In fact, in areas where sickle cell disease is common, this may be the leading cause of diffuse sclerotic bones. In some cases however the osteolytic nidus can be visible on the radiograph (figure). Usually new bone is added to one side of the cortex only. (see diagnostic imaging pearls). T2-weighted axial MR image demonstrates high signal intensity of the tumor in the metacarpal bone with extension of a lobulated soft tissue mass. Impact of Sclerotic. 2021;216(4):1022-30. Axial T1-weighted MR image shows homogeneous low signal intensity due to the compact bone apposition. Osteosarcoma with interrupted periosteal rection and Codman's triangle proximally (red arrow). Our patient had lytic bone lesions in (femur) long bones and also sclerotic lesions in the pelvic which was . At the 1-year follow-up, the lesion was completely stable and no additional follow-up was recommended in the absence of symptoms. Diffuse bony sclerosis (mnemonic). CT-HU has stronger correlations with DEXA than MRI measurements. Osteoblastic metastases (2) The images show on the left a typical osteolytic NOF with a sharp sclerotic border. Radiographically, GCTs are eccentrically located radiolucent lesions with well-defined lytic 1B margins and geographic bone destruction. Classic ground glass appearance of the bone. 11. Bone cements such as polymethyl methacrylate and calcium phosphates have been widely used for the reconstruction of bone. If you can find evidence of subchondral collapse or the typical lucent/sclerotic appearance of the necrotic bone in the weight-bearing bone, then osteonecrosis becomes a much more likely diagnosis. (2005) ISBN: 9780721602707 -. Plain films typically reveal lesions with moth-eaten or permeative pattern of the transition zone with irregular cortical destruction and an interrupted periosteal reaction with soft tissue extension. The sclerotic lesion in the humeral head could very well be a benign enchondroma based on the imaging findings. Fibrous dysplasia, enchondromas, EG, Mets and myeloma, Hyperparathyroidism, Infection. Mnemonic for multiple oseolytic lesions: FEEMHI: Ahuja S & Ernst H. Osteoblastic Bone Metastases in Medullary Thyroid Carcinoma. A periosteal chondroma may have the same imaging characteristics, however, these are almost always much smaller. This is opposed to myositis ossificans which may present very close to the cortical bone, but maturation develops from the center to the periphery. Solitary sclerotic bone (osteosclerotic or osteoblastic) lesions are lesions of bone characterized by a higher density or attenuation on radiographs or computer tomography compared to the adjacent trabecular bone. A surface osteosarcoma could be considered in the differential diagnosis. Centrally there is an ill-defined osteolytic area. In this article we will discuss a systematic approach to the differential diagnosis of bone tumors and tumor-like lesions. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. The contour of the subchondral bone plate was maintained until day 3, but it was absorbed just under the cartilage defect from day 7 to 14. 12. There are two patterns of periosteal reaction: a benign and an aggressive type. The benign type is seen in benign lesions such as benign tumors and following trauma. On the left three bone lesions with a narrow zone of transition. Sclerotic metastases arise from . Sclerotic bone lesions are commonly detected by abdominal MRI in children with tuberous sclerosis complex. Acute osteomyelitis is characterised by osteolysis. 2016;207(2):362-8. Radionuclide bone scan shows a classic "double density" sign of osteoid osteoma located in the tibia: markedly increased radioactivity in the center ( arrow) is related to the nidus, less active areas ( arrowheads) represent reactive sclerosis. A periosteal reaction is a non-specific reaction and will occur whenever the periosteum is irritated by a malignant tumor, benign tumor, infection or trauma. 1, The classic bone island has a spiculated or paintbrush border and is much denser on CT than a osteoblastic metastasis. It classically presents with nocturnal pain in young patients, painful scoliosis, and marked relief from NSAIDs (nonsteroidal anti-inflammatory drugs). Reference article, Radiopaedia.org (Accessed on 02 Mar 2023) https://doi.org/10.53347/rID-10490, {"containerId":"expandableQuestionsContainer","displayRelatedArticles":true,"displayNextQuestion":true,"displaySkipQuestion":true,"articleId":10490,"questionManager":null,"mcqUrl":"https://radiopaedia.org/articles/sclerotic-bone-metastases/questions/1747?lang=us"}. As current recommendations for tuberous sclerosis complex surveillance include renal MR performed i 33.1a) and sagittal short tau inversion recovery (STIR; Fig. Notice that the mineralization is predominantly in the periphery of the mass and that there is a lucent zone between the mass and the cortical bone. Here a patient with a broad-based osteochondroma. If the lesion grows more rapidly still, there may not be time for the bone to retreat in an orderly manner, and the margin may become ill-defined. When considering hyperparathyroidism, look for evidence of subperiosteal bone resorption. If the process is slower growing, then the bone may have time to mount an offense and try to form a sclerotic area around the offender. Here an illustration of the most common sclerotic bone tumors. BallooningBallooning is a special type of cortical destruction.In ballooning the destruction of endosteal cortical bone and the addition of new bone on the outside occur at the same rate, resulting in expansion. 2 ed. Here on a radiograph the typical calcifications in the chondroid matrix of an enchondroma. In juxta-articular localisation, the reactive sclerosis may be absent. Calcifications or mineralization within a bone lesion may be an important clue in the differential diagnosis. Notice that there are small areas of ill-defined osteolysis. Rapid growth of the mineralized mass is not uncommon. Should be included in the differential diagnosis of young patient with multiple lucent lesions (Langerhans cell histiocytosis). When considering trauma as a cause for sclerotic lesions, remember to check and see if the areas involved are areas in the typical distribution for stress fractures. These are inert filled-in non-ossifying fibromas. At Henry Ford Orthopaedics in Chelsea our mission is to provide personalized treatment plans specific to each patient, to ensure the best possible outcome. Results: In 24 patients, 52 new sclerotic lesions observed during therapy were selected for re-evaluation of conventional radiographs and bone scans. A mnemonicfor remembering the causes of diffuse bony sclerosis is: ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. The role of imaging in SN lymphomas is to identify the primary site of disease, site for biopsy and to map the lesion in its entirety in cases of patients undergoing radiotherapy [ 15, 21 ]. Urgency: Routine. Distinction of Long Bone Stress Fractures from Pathologic Fractures on Cross-Sectional Imaging: How Successful Are We? What does it mean that a lesion is sclerotic? Small area of lucency with adjacent sclerosis at the distal right medial femoral metaphysis that could relate to enthesopathic change or remodeling of a fibroxanthoma of bone.. The differential diagnosis mostly depends on the review of the conventional radiographs and the age of the patient. Paget disease is a chronic disorder of unknown origin with increased breakdown of bone and formation of disorganized new bone. Consider peripheral chondrosaroma in growing osteochondromas with or without pain after closure of the physeal plate. CT of Sclerotic Bone Lesions: Imaging Features Differentiating Tuberous Sclerosis Complex with Lymphangioleiomyomatosis from Sporadic Lymphangioleiomymatosis1. Infections and eosinophilic granulomaInfections and eosinophilic granuloma are exceptional because they are benign lesions which can mimick a malignant bone tumor due to their aggressive biologic behavior. Cartilaginous tumors in particular chondrosarcoma may show endosteal scalloping, while a bone infarct does not. Less dense on CT and more heterogeneous than bone islands. Scuba Certification; Private Scuba Lessons; Scuba Refresher for Certified Divers; Try Scuba Diving; Enriched Air Diver (Nitrox) Usually stress fractures are easy to recognize. In an older patient one should first consider an osteoblastic metastasis. 2, The primary utility of the bone scan is that if there is no increased uptake, sclerotic metastatic disease is highly unlikely; therefore, the lesion can be considered most likely a bone island and follow-up radiographic imaging obtained. Notice the homogeneous thickening of the cortical bone. Magnetic resonance imaging of subchondral bone marrow lesions in association with osteoarthritis. 2nd most common primary bone tumor and highly malignant. Kimura T. Multidisciplinary Approach for Bone Metastasis: A Review. 1. Moreover, questions such as the .
