The objective of our study was to characterize patterns of calcifications in synovial sarcoma.

The presence of fine, stippled calcifications in a soft-tissue mass should raise suspicion for synovial sarcoma. These calcifications can coalesce to a deposit that mimics hydroxyapatite deposition disease or soft-tissue osteosarcoma. Spicules of calcification were a less common finding in our series; the appearance of spicules in synovial sarcomas overlaps with that of other soft-tissue sarcomas such as soft-tissue osteosarcoma and liposarcoma.

    ABSTRACT: Objective: The purpose of this review is to describe the imaging features, common and uncommon sites, metastatic pattern, and treatment response of synovial sarcoma. Conclusion: Synovial sarcoma primarily occurs in young adults, most commonly in the lower extremities; presents as a large, noninfiltrative, well-circumscribed mass adjacent to joints, often with punctuate calcifications; and may exhibit a triple signal pattern on T2-weighted images. Small synovial sarcomas can mimic benign lesions. This tumor has a propensity for late local recurrence and metastasis, most commonly to lung.

    ABSTRACT: Objective This study was conducted to describe the imaging features and clinical manifestations in acute calcific tendinitis (CaT) of the gluteus medius muscle (GMe). Methods A retrospective analysis was conducted, aimed at six patients with acute calcific tendinitis of the gluteus medius muscle (CaT-GMe) who were seen between March, 2011 and December, 2012. Clinical presentations, radiologic data (radiography, CT, and MRI), and laboratory reports were all subject to review. Results All patients presented with pain and decreased range of motion (ROM) at the hip. Two of the six experienced pain in the anterolateral thigh and groin, with antalgic gait (anterior group). The other four complained of low back, buttock, and posterolateral thigh pain, accompanied by of difficulty standing and antalgic gait (posterior group). Edema within the GMe or effusion surrounding the muscle was regularly identified on MRIs. Calcific deposits were conspicuous in gluteus medius tendon attachments to lateral (anterior group) and superoposterior (posterior group) facets of greater trochanter on radiography, CT, or MRI. Complete resolution of symptoms was uniformly achieved in 5 to 10 days with conservative management. Conclusions Acute CaT-GMe should be considered in any patient suffering lateral hip pain (with either groin or low back pain) and ROM limitation. Images of the hip characteristically show edema of gluteus medius and calcifications lateral or superior to greater trochanter.

    ABSTRACT: Imaging plays an important role in the diagnosis, biopsy, staging, and follow-up of patients with soft tissue sarcomas. General principles of imaging diagnosis of soft-tissue sarcomas using radiography, ultrasound, CT, MRI, and PET/CT will be discussed, with emphasis on the role of location, internal fat and calcification, presence of myxoid stroma, and enhancement characteristics.
