A 51 year-old man presented with a 10-year history of a painless, slowly growing mass (35 x 25 x 15 min) in the right temporal fossa. The T1-weighted image on magnetic resonance imaging demonstrated a partial, low-signal intensity lesion with high intensity in the lower part and significant enhancement with contrast medium. The tumor, which lay within the temporal muscle, was totally excised, and histological examination confirmed the lesion to be an intramuscular, cavernous type of hemangioma. The therapeutic options are described.
