Alveolar soft part sarcoma is a rare, highly vascular, soft tissue sarcoma. It usually presents as a slow growing, painless lesion in the lower extremities of young adults. Bone invasion is rare. In this pictorial essay, we present the imaging features, approach to differential diagnosis, and prognosis of alveolar soft part sarcoma, with and without bone invasion.
