A 46-year-old woman was presented with a 20-year history of a painless, slowly-growing mass (6 cm in diameter) at the right parotid region. Magnetic resonance imaging demonstrated hemangioma of the right masseter muscle. The tumor was initially treated with angiography and superselective embolization using polyvinyl alcohol foam (Ivalon). A marked reduction in vascularity with deflation of the lesion occurred.
