Vascular leiomyoma, an uncommon soft tissue extremity lesion: Illustration of MR findings in 2 cases.

Vascular leiomyomas are infrequent benign soft tissue neoplasms arising from vascular wall. These lesions are more frequent in females, predominantly seen in lower extremities presenting as slowly enlarging freely mobile palpable soft tissue lesions, often painful. The role of imaging in small peripheral soft tissue masses is often limited to preoperative mapping with a long list of potential differentials. We are presenting 2 case studies of palpable masses with similar pathology, soft tissue vascular leiomyomas where its MR features can be helpful in inclusion of this entity not only in differential diagnosis of enhancing small peripheral soft tissue masses but can suggest a diagnosis in appropriate clinical scenario.
