Abstract:
Intramuscular hemangiomas are benign vascular lesions of skeletal muscle and constitutes less than 1% of all hemangiomas. Of all intramuscular hemangiomas, 13-25% occur in the head and neck, presenting lesions of enlarging soft tissue mass associated with pain. Usually they do not exhibit cutaneous changes, such as bluish skin discoloration as seen in cutaneous and superficial subcutaneous lesions. Because of their infrequency, deep location and unfamiliar presentation, intramuscular hemangomas are seldom correctly diagnosed clinically. We encountered a case of intramasseteric hemangioma in a 14-year-old female. She presented intermittent painful swelling on the right preauricular area. Sialography showed a multiple calcified lesion of the soft tissue, while CT scan and MRI showed a tumor mass lying in the masseter muscle. Angiography showed blush lesion but no tumor feeding arteries. After 6 months of intra-lesional sclerosing therapy with alcohol, total regression of tumor was obtained. As we experienced in this case, percutaneous sclerotherapy with alcohol could be the first therapeutic alternative.
