In this study, we report a rare case of multiple intramuscular hemangioma. A 30-year-old man complained of right elbow joint pain. Magnetic resonance imaging showed abnormal shadows within the supinator muscle and the triceps muscle. We removed the two tumors completely. The pathological diagnosis was intramuscular hemangioma. Later, five lesions of hemangioma in the right hemiarm and hemitorso were detected by MRI or microscopic examination: medial upper arm, M. pectoralis major, M. deltoid and M. serratus anterior (two lesions). We diagnosed this case as multiple intramusclar hemangioma.
