摘要
Intraneural hemangioma is extremely rare, and there are no reported cases that describe multilevel ulnar neuropathy caused by multiple intraneural hemangiomas in a single nerve. We report the case of a 47-year-old man with multilevel ulnar neuropathy caused by multiple intraneural hemangiomas in an ipsilateral ulnar nerve. Multilevel ulnar neuropathy was detected by electrodiagnosis, and intraneural hemangiomas were suggested by ultrasonographic evaluation before the operation. Careful surgical excision under an operating microscope ameliorated the patient's symptoms without recurrence. Muscle Nerve 41: 562-566, 2010
