Abstract
A case of multiple hemangiomas of the cauda equina nerve roots, conus medullaris, and lower spinal cord is described. The 74-year-old male patient presented with a 9-month history of progressive bilateral leg weakness. He had a history of lymphoma at the age of 39 years and renal cell carcinoma in his early 40s. Neither disease was evident at the time of this presentation. A magnetic resonance image revealed multiple enhancing nodules in the cauda equina region as well as on the pial surface of the lower thoracic spinal cord and conus medullaris. The patient underwent an L2-3 laminectomy. Cauda equina nerve roots were found to be studded with numerous purple nodules, the largest measuring 6 to 8 mm. The nodules were adherent to nerve roots from which they could not be resected. Two lesions were histologically examined and found to be capillary hemangiomas. Twelve months into an uneventful postoperative course, the patient is neurologically unchanged. This unique case might represent a distinct form of hemangiomatosis confined to the cauda equina nerve roots and spinal cord.
