Spinal intradural capillary hemangioma.

BACKGROUND: Capillary hemangiomas are typically superficial lesions found in the skin or mucosa of the head and neck, but intradural locations are rare. We report a case of the spinal intradural capillary hemangioma of the lumbar spine with a review of the pertinent literature.

CASE DESCRIPTION: A 59-year-old man presented with a 3-month history of low back pain and left leg pain. On examinations, the patient was shown to have paresthesia in the left L4, L5, and S1 dermatome and a diminution of the left knee jerk. Magnetic resonance imaging revealed an approximately 2-cm intradural enhancing lesion at the level of the L1-2 disk space. Laminectomy of L1-2 was performed for tumor removal. A reddish mass was covered by matted adherent nerve roots and derived its blood supply from radicular vessels. Complete excision was accomplished. Histologic diagnosis was capillary hemangioma. After operation, the patient's symptoms were improved.

CONCLUSION: We experienced a rare spinal intradural vascular tumor of the lumbar spine. Histologic diagnosis was capillary hemangioma. We report a rare case of spinal intradural capillary hemangioma of the lumbar spine.
