Intramuscular vascular anomalies are rare congenital hamartomatous lesions. Less than 1% of these occur in skeletal muscle out of which 15% arise in head and neck musculature. In the head and neck region, masseter muscle is the most common site. It accounts for about 5% of intramuscular vascular malformations. They are present from birth but are clinically apparent during infancy and childhood and occasionally during adulthood. Due to its location it is often mistaken for a parotid swelling. The usual treatment of choice is surgical excision with a margin. This is associated with loss of motor function, hemorrhage, nerve damage. Intralesional sclerotherapy, embolization are nonsurgical alternatives for treatment of slow flow venous malformations. Sclerotherapy can be used solely in multiple sittings or as an adjunct to surgery. This article presents a case report of a 28-year-old male with recurrent intramuscular vascular malformation in the masseter muscle, which was successfully treated by ethanol sclerotherapy.
