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. Cortical destruction (3) UW Radiology Sclerotic Lesions of Bone <-Lucent Lesions of Bone | Periosteal Reaction-> What does it mean that a lesion is sclerotic? Chrondroid tumors are more frequently encountered than bone infarcts. 2018;10(6):156. Secondary bone cancer is much more common than primary bone . Brant WE, Helms CA. 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). 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. This could very well be an enchondroma. Our patient had lytic bone lesions in (femur) long bones and also sclerotic lesions in the pelvic which was . Gadolinium is usually minimal or absent (see right image). (2005) ISBN: 9780721602707 -. by Clyde A. Helms 14. A cold bone scan is helpful in distinguishing the bone island from a sclerotic metastasis, whereas a warm bone scan is nondiagnostic. The image on the right is of a different patient who has an old NOF that shows complete fill in. Sclerotic bone lesions as a potential imaging biomarker for the diagnosis of tuberous sclerosis complex Authors Susanne Brakemeier 1 , Lars Vogt 2 , Lisa C Adams 2 , Bianca Zukunft 3 , Gerd Diederichs 2 , Bernd Hamm 2 , Klemens Budde 3 , Kai-Uwe Eckardt 3 , Marcus R Makowski 2 4 Affiliations Osteoblastic metastases (2) T2-weighted MR image reveals a lobulated mass with high signal intensity. DD: old SBC. growth of osteohondroma in skeletally mature patients, irregular or indistinct surface of lesions, soft tissue mass with scattered or irregular calcifications. 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. In fact, in areas where sickle cell disease is common, this may be the leading cause of diffuse sclerotic bones. Melorrheostosis is a dysplasia of the bone, characterized by apposition of mature bone on the outer or inner surface of cortical bone. Cortical destruction is a common finding, and not very useful in distinguishing between malignant and benign lesions. Well, generally, it means that it is due to a fairly slow-growing process. Contrast-enhanced T1-weighted MR image demonstrates heterogeneous enhancement of the mass with extensive surrounding edema. The contour of the involved bone is usually normal or with mild expansive remodelling. Biopsy revealed dedifferentiated chondrosarcoma. 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. 4 , 5 , 6. 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. Bone scintigraphy can be either negative or show limited uptake. Imaging: 1, The classic bone island has a spiculated or paintbrush border and is much denser on CT than a osteoblastic metastasis. Here, we showed that sBT values are higher in patients presenting 496 with bone loss . CT of Sclerotic Bone Lesions: Imaging Features Differentiating Tuberous Sclerosis Complex with Lymphangioleiomyomatosis from Sporadic Lymphangioleiomymatosis1. Giant cell bone tumors are usually benign (not cancerous) but the malignant form can affect the legs, especially near the knees. Click here for more examples of enchondromas. Brant WE, Helms CA.

Here a lesion in the epiphysis, which was the result of post-traumatic osteonecrosis. Here CT-images of a patient with prostate cancer. 1. 1. Osteosarcoma (2) Non-ossifying fibroma (NOF) can be encoutered occasionally as a partial or completely sclerotic lesion. The MR image shows that the lesion has lobulated contours and nodular enhancement. Clinically relevant bone metastases are a major cause of morbidity and mortality for prostate cancer patients. Macedo F, Ladeira K, Pinho F et al. Osteoblastic Metastatic Lesions. Confavreux C, Follet H, Mitton D, Pialat J, Clzardin P. Fracture Risk Evaluation of Bone Metastases: A Burning Issue.

Growth of the osteochondroma takes place in the cap, corresponding with normal enchondral growth at the growth plates. Typically a NOF presents as an eccentric well-defined lytic lesion, usually found as a coincidental finding. (2007) ISBN: 9780781779302 -. Click here for more information about bone island. Fibro-osseous lesion like fibrous dysplasia. 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 Mirels H. Metastatic Disease in Long Bones: A Proposed Scoring System for Diagnosing Impending Pathologic Fractures. Notice the numerous predominantly osteoblastic metastases. It is a feature of malignant bone tumors. Osteosarcoma, chondrosarcoma, and Ewing's sarcoma are the most common types of bone cancer. Unable to process the form. In some locations, such as in the humerus or around the knee, almost all bone tumors may be found. The differential diagnosis of bone lesions that result in bony sclerosis will be given. Detecting a benign periosteal reaction may be very helpful, since malignant lesions never cause a benign periosteal reaction. 13. However, a specific density range has not been specified for those terms 1. The zone of transition only applies to osteolytic lesions since sclerotic lesions usually have a narrow transition zone. (see diagnostic imaging pearls). If the disorder it is reacting to is rapidly progressive, there may only be time for retreat (defense). Here a patient with a mineralized mass in the soft tissues. In patients Many important signaling . 8. Halo of increased signal on T2 W images about the low signal central lesion is suggestive of metastatic disease. Amsterdam: Elsevier, 1993. Once we have decided whether a bone lesion is sclerotic or osteolytic and whether it has a well-defined or ill-defined margins, the next question should be: how old is the patient? A bone island larger than 1 cm is referred to as a giant bone island (12). 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. On the right T2-WI with FS of same patient.. Infection may be well-defined or ill-defined osteolytic, and even sclerotic. Plain radiograph and coronal T1-weighted contrast-enhanced fat-suppressed MR image of a mixed lytic and sclerotic lesion of the distal femoral diaphysis. Conclusion. Ossifications or calcifications can be present in variable amounts. 2010;35(22):E1221-9. Less dense on CT and more heterogeneous than bone islands. 2021;50(5):847-69. The benign type is seen in benign lesions such as benign tumors and following trauma. The zone of transition is the most reliable indicator in determining whether an osteolytic lesion is benign or malignant (1). O'Sullivan G, Carty F, Cronin C. Imaging of Bone Metastasis: An Update. Imaging of skull vault tumors in adults: Author: Pons Escoda, Albert Naval Baudin, Pablo . by Clyde A. Helms Based on the morphology and the age of the patients, these lesions are benign. MRI of the sacrum: axial T1-weighted (T1w; Fig. 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. There are two tumor-like lesions which may mimic a malignancy and have to be included in the differential diagnosis. 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.

Sclerotic bone lesions at abdominal magnetic resonance imaging in children with tuberous sclerosis complex. A 30-year-old woman underwent a CT of the pelvis for endometriosis and an incidental lesion was found in the sacrum. (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. Consider peripheral chondrosaroma in growing osteochondromas with or without pain after closure of the physeal plate. Radiographically, GCTs are eccentrically located radiolucent lesions with well-defined lytic 1B margins and geographic bone destruction. This is extremely common in Pagets disease but extremely uncommon with a blastic metastasis. In the subchondral bone, the number of TRAP-positive cells peaked on day 14. Non-ossifying fibroma which has been filled in. This shows that differentiating a tumor from a reactive proces scan be quite difficult in some cases. There is no calcification and lesions may be expansile. The differential diagnosis of bone lesions that result in bony sclerosis will be given. At Henry Ford Orthopaedics in Chelsea our mission is to provide personalized treatment plans specific to each patient, to ensure the best possible outcome. AJR 1995;164:573-580, Online teaching by the Musculoskeletal Radiology academic section of the University of Washington, by Theodore Miller March 2008 Radiology, 246, 662-674, by Nancy M. Major, Clyde A. Helms and William J. Richardson. Sclerotic bone metastases typically present as radiodense bone lesions that are round/nodular with relatively well-defined margins 3. Particularly chronic osteomyelitis may have a sclerotic appearance. On the left three bone lesions with a narrow zone of transition. Notice the resemblance to a juxtacortical mass in another patient (right), which was a biopsy proven parosteal osteosarcoma. 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. Bker S, Adams L, Bender Y et al. Here a radiograph of the pelvis with a barely visible osteoblastic metastasis in the left iliac bone (blue arrow). by Mulder JD et al Most commonly originate from prostate and breast cancer and less frequently from lung cancer, lymphoma or carcinoid. 2022;51(9):1743-64. Diffuse bony sclerosis (mnemonic). (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 ). 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. Even though plain X-ray and CT would typically be used to follow a suspected bone island, MRI was chosen as the follow-up modality because the sacrum is an area not well seen on plain films due to overlying bowel gas and concern regarding radiation dose from multiple CT scans to the pelvis of a 30-year-old woman. Reference article, Radiopaedia.org (Accessed on 02 Mar 2023) https://doi.org/10.53347/rID-21100, Mnemonic for focal sclerotic lesions (mnemonic). Complete envelopment may occur. 5. More uniform cortical bone destruction can be found in benign and low-grade malignant lesions. Usually it is a lesion of childhood or young adults. There are no calcifications. Axial T1-weighted MR image shows homogeneous low signal intensity due to the compact bone apposition. Radiographs are specific but suffer from low sensitivity 1. AJR Am J Roentgenol. Parkinson's disease, multiple sclerosis, brain tumors and brain trauma [2]. {"url":"/signup-modal-props.json?lang=us"}, Niknejad M, Bell D, Tatco V, et al.

The most common focal metastatic lesions originate from the breast (37%), lung (15%), kidney (6%), and thyroid (4%) 43. Lippincott Williams & Wilkins. Enchondroma, the most commonly encountered lesion of the phalanges. Strahlenther Onkol. In skeletally mature patients, GCTs begin in the metaphysics and extend deep to the subchondral bone plate of the articular surface. Lets apply the good old universal differential diagnosis to sclerotic bone lesions. The radiological report should include a description of the following 2: location and size including the whole extent of disease load, pain attributable to the lesion (if known), Treatment of bone metastases, in general, is usually planned by a multidisciplinary team 10.
