Low flow vascular malformations are typically treated with ultrasound-guided percutaneous sclerotherapy, but not all of these lesions are visible sonographically. MR guided focused ultrasound (MRgFUS) combines the ability of MRI to delineate these tumors with the use of FUS to ablate the tumor non-invasively. We report our technical and clinical results after using MRgFUS to treat four patients with small intramuscular low flow vascular malformations in the lower extremities.
