OPERATIVE MANAGEMENT OF SPINAL HEMANGIOBLASTOMA

Hemangioblastomas occur in 2% to 15% of reported series of intramedullary spinal cord tumors. They are benign, highly vascular tumors that can be cured with surgical resection. Complete removal of these tumors with low morbidity is possible with current microneurosurgical techniques and a thorough understanding of the typical relationship of the tumor to adjacent neural structures. We describe our experience with 16 intramedullary and 2 lumbosacral nerve root hemangioblastomas and review the relevant published literature. A detailed discussion of the operative technique is provided along with an operative video. Three illustrative cases are used to demonstrate clinical considerations that can arise with these tumors, including surgery during pregnancy, symptoms related to syrinx or syringomyelia, and postoperative consequences of neurological deficits.
