Angioleiomyoma of the Extremities: Findings on Ultrasonography and Magnetic Resonance Imaging

Abstract

Angioleiomyoma of the extremities is usually a well-circumscribed oval mass with a homogeneous echo texture and occasionally hypoechoic protrusions on US and shows heterogeneous enhancement with occasionally enhancing structures on one or both ends of the mass on MRI. Therefore, it should be included in the differential diagnosis of a soft tissue mass that has protruding structures from one or both ends.
