Hemangioma in the head and neck often arises in the cheek membrane, tongue, and lips. It is rarely generated in the masseter or trapezius muscle. We encountered a case of cavernous hemangioma in the masseter muscle accompanied by a venous stone. A 26-year-old female patient with a chief complaint of swelling in the right mandibular angle was referred to our department. The present clinical couse showed a 3-year history of repeated swelling of the right jaw every 2 or 3 months. Once the lesion became swollen, it was accompanied by sharp pain and the swelling continued for about one week. A soft mass measuring 30×17 mm was accompanied by pain, and two hard masses were detected within the lesion. The
ramera-like calcification was detected by simple X-ray examination and the lesion was diagnosed as hemangioma accompanied by a venous stone. MRI was useful for diagnosis. Moreover, angiography of the external carotid artery was performed and the findings comfirmed that the nutritional blood vessel was the facial artery.
Key words : hemangioma, masseter muscle, MRI, angiography
