We report a case of radial neuropathy developed in a patient with intramuscular hemangioma. A 19-year-old man had shown the sudden onset of swelling and pain in his left upper arm and then wrist drop came out three days after onset of symptoms. He had been diagnosed with intramuscular hemangioma of his left upper arm three years ago. The electrodiagnostic study showed some or profuse abnormal spontaneous activities without motor unit action potentials in most muscles innervated by radial nerve except for triceps brachii. The upper arm MRI revealed increased radial nerve diameter although the surrounding hemangioma size decreased. The possibility of hemangioma-related inflammatory neuropathy was reviewed.
