흉쇄유돌근에 발생한 근육 내 혈관종: 흔하지 않은 경부 종물

Abstract

Hemangiomas are the most common benign tumors in infancy, occurring most often on cutaneous and mucosal surfaces. Although less than 1% of hemangiomas occur in skeletal muscle, 15% of intramuscular hemangiomas arise in the head and neck musculature. Less than 10 cases of the sternocleidomastoid muscle have been reported in the English literatures. The masseter muscle is most commonly involved in the head and neck. Clinically, these tumors are present as distinct, localized, rubbery swelling. Neck computed tomography scan with enhancement may suggest a vascular mass within the muscle while angiography may detect feeding arteries in large intramuscular hemangiomas. The treatment of the hemangiomas is based on location, accessibility, depth of invasion, age, and cosmetic considerations. The optimal treatment is complete wide resection including the cuff of surrounding muscle. We report a case of hemangioma that occurred in the sternocleidomastoid muscle along with a with literature review.
