A review of 30 pathologically proven synovial sarcomas demonstrated highly variable imaging features, with up to one-third showing commonly benign features that can lead to delayed diagnosis.
What are the imaging features of synovial sarcomas?
Synovial sarcomas can present with highly variable imaging features, including benign-appearing solid or cystic lesions in up to one-third of cases, which can lead to delayed diagnosis.
Synovial sarcomas are malignant soft-tissue tumors that typically affect young patients. They can arise from nearly anywhere in the body, most commonly the extremities, head and neck, and thorax. The imaging features are highly variable and depend on the anatomic origin. Most lesions present as large aggressive heterogeneous masses containing hemorrhagic and cystic foci, often with calcification. However, up to one-third of lesions have commonly benign features and can appear homogeneously solid or cystic. Especially in these cases, their innocuous imaging and clinical presentation can lead to delayed diagnosis. Therefore, knowledge of the imaging spectrum is crucial to ensuring adequate follow-up or timely pathologic sampling. We reviewed 30 pathologically proven cases in various anatomic sites from our institution to illustrate these characteristics.
Wang et al. (Tue,) conducted a review in Synovial sarcomas (n=30). Imaging features was evaluated on Imaging characteristics.
