. 6. Plain radiograph and coronal T1-weighted contrast-enhanced fat-suppressed MR image of a mixed lytic and sclerotic lesion of the distal femoral diaphysis. 2018;2018:1-5. Benign periosteal reaction Secondary bone cancer is much more common than primary bone . UW Radiology Sclerotic Lesions of Bone <-Lucent Lesions of Bone | Periosteal Reaction-> What does it mean that a lesion is sclerotic? Ahuja S & Ernst H. Osteoblastic Bone Metastases in Medullary Thyroid Carcinoma. They usually affect posterior vertebral elements and their number and size increase with age. Growth of osteochondroma in skeletally mature patient, Irregular or indistinct surface of lesions, focal lucent regions in interior of lesions, presence of soft tissue mass with scattered or irregular calcifications. Osteoblastic Metastatic Lesions. 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. Here an illustration of the most common sclerotic bone tumors. Macedo F, Ladeira K, Pinho F et al. After an injury, different types of fluid can build up in a bone. The differential diagnosis of solitary sclerotic bone lesions can be narrowed down according to the following factors 1-3: cartilaginous matrix (rings and arcs appearance). The homogeneous enhancement in the upper part with edema and cortical thickening are not typical for a low-grade chondrosarcoma. Osteoid matrix in osseus tumors like osteoid osteomas and osteosarcomas. MR usually shows a large amount of reactive changes in bone and soft tissue. Brant WE, Helms CA. You can then customize the above differential for whichever pattern of sclerosis that you see. Wide zone of transition Reference article, Radiopaedia.org (Accessed on 02 Mar 2023) https://doi.org/10.53347/rID-8429. Abbreviations used: The most important determinators in the analysis of a potential bone tumor are: It is important to realize that the plain radiograph is the most useful examination for differentiating these lesions.CT and MRI are only helpful in selected cases. There is no calcification and lesions may be expansile. Bone reacts to its environment in two ways either by removing some of itself or by creating more of itself. Bone flare phenomenon was well described on bone scans; a study 25 revealed the appearance of new or worsening bone sclerosis at 3-month CT assessment in three of 67 castration-resistant prostate cancer (CRPC) patients undergoing systemic treatment. A disadvantage of MRI is that the detection is poor in bones with a small marrow cavity such as the ribs and these bones are better investigated with CT 2,3. Generic Differential Diagnosis of Sclerotic Bone Lesions. Case 2: sclerotic metastases from prostate cancer, Generalised increased bone density (mnemonic). Sclerotic jaw lesions are not rare and are frequently encountered on radiographs and computed tomography (CT). Sclerotic or blastic bone metastases can arise from a number of different primary malignancies including prostate carcinoma (most common), breast carcinoma (may be mixed), transitional cell carcinoma (TCC), carcinoid, medulloblastoma, neuroblastoma, mucinous adenocarcinoma of the gastrointestinal tract (e.g., colon carcinoma, gastric carcinoma), Most of the time, sclerotic lesions are benign. Occasionally slowly enlargement can be seen. 3. In fact, in areas where sickle cell disease is common, this may be the leading cause of diffuse sclerotic bones. Society of Skeletal Radiology- White Paper. 2019;290(1):146-54. 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.

Sclerotic Lesions of the Spine 1311. predominant hypointensity on all imaging sequences mimicking a sclerotic process due to a variety of fac- . Here on a radiograph the typical calcifications in the chondroid matrix of an enchondroma. Osteoid matrix (white arrows). 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. At the periphery of the infarct a zone of relative high signal intensity on T2WI may be found. brae in keeping with diffuse bone infarcts. {"url":"/signup-modal-props.json?lang=us"}, Knipe H, Yap J, Masters M, et al. When you are considering osteonecrosis in your differential diagnosis, look at the joints carefully. Metastases are the most common malignant bone tumors. This occurs in early knee osteoarthritis and indicates the potential for cartilage loss and misalignment of a knee compartment. Density measurements on CT scan revealed greater than 1,000 HU throughout the lesion. In the article Bone Tumors - Differential diagnosis we discussed a systematic approach to the differential diagnosis of bone tumors and tumor-like lesions. ADVERTISEMENT: Supporters see fewer/no ads. mutation, and both sclerotic and lytic bone lesions together for the first time. The term bone infarction is used for osteonecrosis within the diaphysis or metaphysis. Lets apply the good old universal differential diagnosis to sclerotic bone lesions. colon carcinoma, gastric carcinoma), ADVERTISEMENT: Supporters see fewer/no ads. Surrounded by a prominent zone of reactive sclerosis due to a periosteal and endosteal reaction, which may obscure the central nidus. 2003;415(415 Suppl):S4-13. 3. Chrondroid tumors are more frequently encountered than bone infarcts. Gadolinium is usually minimal or absent (see right image). Osteoma consists of densely compact bone. When a reactive process is more likely based on history and imaging features, follow-up is sometimes still needed. WSI digital slide: https://kikoxp.com/posts/4606. The bone scan is also helpful to look for additional sites of increased uptake that may not have been imaged, such as multiple nontraumatic rib, calvarial, or long bone lesions, which would strongly suggest the diagnosis of metastatic disease. Click here for more examples of eosinophilic granuloma. This is opposed to myositis ossificans which may present very close to the cortical bone, but maturation develops from the center to the periphery. Differential diagnosis based on the periosteal reaction and the extensive edema: Here a patient with a juxtacortical sclerotic mass of the proximal humerus (left). Notice that the cortical bone extends into the lesion. 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. <-Lucent Lesions of Bone | Periosteal Reaction->. 4, Although usually stable in size, bone islands may increase or decrease in size or disappear. Intense uptake on bone scintigraphy as we would expect in high grade chondrosarcoma. Less dense on CT and more heterogeneous than bone islands. 7. Infection is seen in all ages. Wayne State University, Orthopaedic Surgery, MI, 2007 University of Texas Southwestern Medical School, Surgery, TX, 2002 In general, they're slow-growing.. Moreover, questions such as the . Bone scan shows no high activity, opposed to low-grade intraosseous osteosarcoma. (2005) ISBN: 9780721602707 -. Some prefer to divide patients into two age groups: 30 years. In this chapter, we will discuss key imaging features that strongly indicate the lesion is benign and those that warn further evaluation is warranted. Unable to process the form. In this chapter, we will discuss key imaging features that strongly indicate the lesion is benign and those that warn further evaluation is warranted. Imaging of skull vault tumors in adults: Author: Pons Escoda, Albert Naval Baudin, Pablo . A T1w/T2-weighted (T2w) hypointense nonexpansile lesion is seen involving the sacrum (asterisk). There are two kinds of mineralization: Chondroid matrix About Us; Staff; Camps; Scuba. There were other features that favored the diagnosis of a low-grade chondrosarcoma like a positive bone scan and endosteal scalloping of the cortical bone on an MRI (not shown). Home. 2016;207(2):362-8. 8. 1 When the vertebral lesion has no benign features, especially in the older adult patient, metastatic disease is always a significant consideration. More uniform cortical bone destruction can be found in benign and low-grade malignant lesions. Classic ground glass appearance of the bone. Both of these entities may have an aggressive growth pattern. Radiologe. 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. A high grade chondrosarcoma must be considered in the differential diagnosis. The differential diagnosis of bone lesions that result in bony sclerosis will be given. 2. The most common focal metastatic lesions originate from the breast (37%), lung (15%), kidney (6%), and thyroid (4%) 43. At the 1-year follow-up, the lesion was completely stable and no additional follow-up was recommended in the absence of symptoms. Symptoms are usually absent, however, in adult patients with a chondroid lesion in a long bone, particularly of larger size, always consider low-grade chondrosarcoma. Isaac A, Dalili D, Dalili D, Weber M. State-Of-The-Art Imaging for Diagnosis of Metastatic Bone Disease. Rib metastases may be osteolytic, sclerotic, or mixed. There are two patterns of periosteal reaction: a benign and an aggressive type. These lesions were possibly misinterpreted as new when applying WHO criteria. Click here for more examples of chondrosarcoma. The chondroid matrix is of a variable amount from almost absent to dens compact chondroid matrix. Accordingly, growth of osteochondromas is allowed until a patient reaches adulthood and the physeal plates are closed. Bone islands demonstrate uniformly low The image on the right is of a different patient who has an old NOF that shows complete fill in. Hyperdense oval-shaped lesions with spiculated or paintbrush margins, without distortion of the adjacent bony trabeculae. Sclerotic bone lesions are commonly detected by abdominal MRI in children with tuberous sclerosis complex. D'Oronzo S, Coleman R, Brown J, Silvestris F. Metastatic Bone Disease: Pathogenesis and Therapeutic Options. T2-weighted axial MR image demonstrates high signal intensity of the tumor in the metacarpal bone with extension of a lobulated soft tissue mass. Fibrous dysplasia can be monostotic or polyostotic. 9. Here a lesion located in the epi- and metaphysis of the proximal humerus. In breast cancer, metastases may present as lytic lesions that may become sclerotic expressing a favourable response to chemotherapy. Here an image of a patient with chronic osteomyelitis. Check for errors and try again. In 8 of the 24 patients, 17 of 52 new sclerotic lesions (33%) had showed positive uptake on previous bone scans. In the active phase there is multilaminar periosteal reaction and bone and soft tissue edema. The images show on the left a typical osteolytic NOF with a sharp sclerotic border. Solitary lucent lesions in bone with a distinct margin are generally called "geographic" lesions, whether or not they have a sclerotic rim. Detecting a benign periosteal reaction may be very helpful, since malignant lesions never cause a benign periosteal reaction. Eosinophilic granuloma like osteomyelitis, can be a serious mimicker of malignancy (particularly Ewing sarcoma). A Novel Classification System for Spinal Instability in Neoplastic Disease: An Evidence-Based Approach and Expert Consensus from the Spine Oncology Study Group. 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 chondroma may have the same imaging characteristics, however, these are almost always much smaller. On the right T2-WI with FS of same patient.. Multiple enchondromas and hemangiomas are seen in Maffucci's syndrome. 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 . Hall F & Gore S. Osteosclerotic Myeloma Variants. 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. Non-ossifying fibroma which has been filled in. AJR 2000; 175:261-263. 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. Check for errors and try again. Finally, we conclude with a case of an incidentally presenting sclerotic vertebral body lesion. Likewise patients with sclerotic lesions due to various drugs or minerals will tell you what they are taking if you ask them. Semin. Reference article, Radiopaedia.org (Accessed on 02 Mar 2023) https://doi.org/10.53347/rID-21100, Mnemonic for focal sclerotic lesions (mnemonic). Brant WE, Helms CA. 2021;50(5):847-69. In the table the most common sclerotic bone tumors and tumor-like lesions in different age-groups are presented. Enhancement after i.v. 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. Tumor Pathology- Bone Lesion Bone Tumor Osteomyelitis When you identify a bone lesion, follow this basic checklist to help you accurately describe the lesion and narrow your differential diagnosis: Bone Tumors and Tumorlike Conditions: Analysis with Conventional Radiography Theodore T. Miller Radiology 2008 246:3, 662-674 1. Sclerotic bone metastases can arise from several different primary malignancies including 1-3: mucinous adenocarcinoma of the gastrointestinal tract (e.g. This shows that differentiating a tumor from a reactive proces scan be quite difficult in some cases. This solitary, uniformly high-density lesion with neither edema in the surrounding bone marrow nor extension into the surrounding soft tissue most likely represents a giant bone island. The differential for multifocal lesions happens to be identical to that for focal lesions. In the late stage of OA, the main feature is subchondral bone sclerosis, whose microarchitectural characteristics are elevated apparent density, increased bone volume, . The mean and maximum attenuation were measured in Hounsfield units. A Codman's triangle refers to an elevation of the periosteum away from the cortex, forming an angle where the elevated periosteum and bone come together. In Section 2, we give the general technical route for classification, detection and segmentation of multiple-lesion.After that, in Section 3, the paper will review the recognition of multiple-lesion in six organ and tissue areas, including brain, eye, skin, breast, lung, and abdomen. Notice the homogeneous thickening of the cortical bone. A sclerotic border especially indicates poor biological activity. 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. by Mulder JD, et al. DD: juxtacortical chondrosarcoma, parosteal osteosarcoma. In this article we will discuss the differential diagnosis of sclerotic bone tumors and tumor-like lesions in more detail. 7. Materials and Methods Large lesions tend to expand into both areas. The diagnosis was fibrous dysplasia.

Osteosarcoma (2) Cancers (Basel). Parosteal osteosarcoma is a sarcoma that has it's origin on the surface of the bone. The zone of transition only applies to osteolytic lesions since sclerotic lesions usually have a narrow transition zone. In some cases however the osteolytic nidus can be visible on the radiograph (figure). Detection of a solitary sclerotic bone lesion on CT or plain radiograph often creates a diagnostic dilemma. Etiology Calcifications in chondroid tumors have many descriptions: rings-and-arcs, popcorn, focal stippled or flocculent. Scuba Certification; Private Scuba Lessons; Scuba Refresher for Certified Divers; Try Scuba Diving; Enriched Air Diver (Nitrox) 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. 2022;51(9):1743-64. Consider peripheral chondrosaroma in growing osteochondromas with or without pain after closure of the physeal plate. The NK cell type is seen as a sheet of soft tissue in the nasal cavity with bone destruction and erosion without any sclerosis. Uncommonly it can be difficult to differentiate a stress fracture from a pathologic fracture, that occurs at the site of a bone tumor. J Korean Soc Radiol. Infection with a multilayered periosteal reaction. Aggressive periosteal reaction What does it mean that a lesion is sclerotic? Notice that many benign osteolytic lesions that are frequently seen in younger age groups may heal and appear as sclerotic lesions in the middle aged group. There are two tumor-like lesions which may mimic a malignancy and have to be included in the differential diagnosis. Notice that in all three patients, the growth plates have not yet closed. This is especially true when the injury involves the spine, hip, knees, or ankle. Metastases must be included in the differential diagnosis of any bone lesion, whether well-defined or ill-defined osteolytic or sclerotic in age > 40. The use of PET/CT imaging with new radiotracers enables a non-invasive assessment of the presence of the target of treatment in the whole body and provides the possibility to combine functional information with anatomical details. Click here for more information about bone island. Imaging: Usually stress fractures are easy to recognize. Radiographically, GCTs are eccentrically located radiolucent lesions with well-defined lytic 1B margins and geographic bone destruction. Multiple myeloma is a hematologic malignancy of plasma cells that causes bone-destructive lesions and associated skeletal-related events (SREs). 20 yo M w/ 5 cm lytic bone lesion in proximal tibia metaphysis, sharply demarcated w/ sclerotic rim. Mnemonic for multiple oseolytic lesions: FEEMHI: Sclerosing bone dysplasias are skeletal abnormalities of varying severity with a wide range of radiologic, clinical, and genetic features.
