Intramuscular Hemangioma of Temporal Muscle

Abstract

Intramuscular hemangiomas (IMH) are benign vascular neoplasms arising most frequently in skeletal muscles. They usually present themselves as a soft, non-tender soft tissue swelling. Though hemangiomas are the most common benign neoplasms seen in children, they rarely occur in adults. Pathologically, they are characterized by the proliferation of blood vessels within muscles, occurring most frequently in the large muscle of the extremities and trunks. In the head and neck region, the masseter and trapezius muscles are most commonly involved. IMH within the temporal muscle is reported only a few cases until now. A case of IMH of temporal muscle in a 24-year-old male is reported. (Korean J Otorhinolaryngol-Head Neck Surg 2009;52:266-9)
