Intramuscular Myxoma: An Uncommon Tumor with Characteristic Imaging Features - Sonographic, Radiologic, and Pathologic Correlation

Intramuscular myxoma is an uncommon benign soft tissue tumor that may arise from fibroblasts that produce an excessive amount of mucopolysacchrides. It is typically seen in adults in the large muscles of extremities and exhibits typical radiological features on sonography and magnetic resonance imaging. A case of intramuscular myxoma in the left Vastus intermedius is described in a 52-year-old man who presented with gradually increasing swelling in the thigh. The case illustrates characteristic radiologic "bright cap and rim" signs with pathologic correlation.
