Imaging findings of a subcutaneous angioleiomyoma.

Angioleiomyoma is a benign smooth muscle tumor arising from the vessel walls.The tumor can occur anywhere in the body, but is most often seen in the extremities, particularly in the lower leg. The most common presentation is a solitary subcutaneous nodular lesion, which is either painful or painless. We report a rare case of a slowly growing solid angioleiomyoma of the right lower leg in a 34-old-year old man. Although imaging characteristics on MR imaging and ultrasound are nonspecific, angioleiomyoma should be considered in the differential diagnosis when a mobile, slowly growing and well vascularised lesion is encountered in the extremities.
