교근에 발생한 해면상 혈관종 1예

Abstract

Intramuscular hemangiomas are uncommon tumors of the head and neck and when present, the masseter muscle is the most frequently involved site, although constituting only 0.8% of all hemangiomas. Diagnosis of intramuscular hemangioma is extremely difficult even with accurate preoperative imaging because it is not encountered frequently and is often confused with salivary gland stone, parotid neoplasm or other tumors. The definitive diagnosis is made by histological study of the surgical biopsy specimen. Treatment of choice is by complete surgical excision. This is the first case of intramuscular hemangioma of the masseter muscle reported in Korea. So I review the clinical, radiologic, histologic findings and treatment modalities of the intramuscular hemangioma.
