Abstract
Hemangioblastomas are uncommon in the spine, accounting for less than 3% of all spinal cord tumors and occurring even more rarely in the intradural extramedullary vicinity. We present a unique case report of an intradural extramedullary hemangioblastoma. A 62-year-old man presented with a five-month history of neck pain radiating to the left arm. A magnetic resonance imaging (MRI) of the cervical spine revealed a left paracentral contrast-enhancing intradural extramedullary lesion at the C4-C5 level. Surgical options were discussed, and surgery was performed via a posterolateral approach. The lateral masses and facets at the C4 and C5 levels were drilled and the tumor was encountered ventral to the spinal cord. There were multiple nerve roots adherent to the tumor capsule. The tumor was highly vascularized. Analysis revealed a highly vascular lesion with vacuolated tumor cells, positive for inhibin and S100 stains, consistent with a diagnosis of hemangioblastoma. The patient remains intact throughout the post-operative period. Few studies have reported intradural extramedullary spinal hemangioblastomas and purely extramedullary spinal hemangioblastomas of the neuraxis are far less common. Most cases occur in the Japanese population and in patients over the age of 50. By location, extramedullary hemangioblastomas involving the thoracic spine occur in women, while those occurring in men are restricted to the cervical spine or conus medullaris. Complete resection remains the treatment of choice.
