Intraneural capillary hemangioma of the cauda equina

A case of intraneural capillary hemangioma involving the dorsal root of a spinal nerve of the cauda equina is reported. The patient was a 41-year-old man with a 3-month history of intermittent left lumbosciatalgia. MRI and CT myelography showed a space-occupying mass at the level of the cauda equina. Laminectomy of L5 and complete removal of the lesion were performed without neurological problems. The clinical, diagnostic, and therapeutic aspects of hemangiomas of the cauda equina are analyzed.
