Many benign nonneoplastic entities can mimic bone and soft tissue tumors on imaging examinations. Distinguishing between neoplastic and nonneoplastic entities depends on history and physical examination findings and imaging findings, and is an important early step in the patient's overall workup and treatment plan. This article describes some of the(More)
BACKGROUND Our goal was to assess the effectiveness and safety of argon beam coagulation as an adjuvant treatment for primary aneurysmal bone cysts, to reevaluate the adjuvant effectiveness of the use of a high-speed burr alone, and, secondarily, to identify predictors of aneurysmal bone cyst recurrence. METHODS We retrospectively reviewed the records of(More)
We report a case of multifocal metachronous giant cell tumor (GCT) that involved the fibula, tibia, and sacrum of a 15-year-old boy. Multifocal GCT of bone presenting in children is an exceedingly rare phenomenon; however, there is evidence that multifocal GCT presents, on average, at a younger age than solitary GCT. Pediatric radiologists should be aware(More)
Rosai-Dorfman disease is a rare entity predominantly affecting children and young adults, characterized in 83–95% of cases by painless bilateral cervical lymphadenopathy. We report the unusual case of a 41-year-old woman with Rosai-Dorfman disease that presented as a solitary lesion of the radius without other clinical manifestations.
With advances in imaging technology, there has been a significant increase in the number and range of interventional musculoskeletal image-guided procedures. One of the most commonly performed image-guided musculoskeletal interventions is the diagnostic and therapeutic percutaneous aspiration and drainage of multiple types of intra-articular,(More)
The purpose of this review is to illustrate the pertinent clinical and imaging features of extremity sarcomas of uncertain differentiation, including synovial sarcoma, epithelioid sarcoma, clear-cell sarcoma, and alveolar soft part sarcoma. These tumours should be considered in the differential diagnosis when a soft-tissue mass is encountered in the(More)
The poor prognosis for patients with osteosarcoma skip metastases has been established in the literature; however, most of the data in the literature concerning osteosarcoma skip metastases were collected before routine use of magnetic resonance imaging and before the use of modern multiagent chemotherapy regimens. This retrospective multiinstitutional(More)
We report an unusual case of a woman who sought medical attention for a painful mass within her anterolateral left thigh. The patient’s symptoms waxed and waned with her menses. Magnetic resonance imaging revealed a 3 cm mass isointense to muscle and surrounded by a rim of decreased signal intensity on T1–weighted images. T2–weighted images with fat(More)
