Intramuscular hemangiomas of the masseter muscle are uncommon tumors and 
therefore can be difficult to accurately diagnose preoperatively, due to the 
unfamiliar presentation and deep location in the lateral face. A case of 
intramuscular hemangioma of the masseter muscle in a 66-yearold woman is 
presented. Doppler ultrasonography showed a 34× 15 mm hypoechoic and 
hypervascular soft tissue mass in the left masseter muscle, suggesting 
hemangioma. The mass was excised via a lateral cervical incision near the 
posterior border of the mandibular ramus. The surgical wound healed well without 
complications.
