Spinal hemangioblastomas are benign, and total surgical resection is the standard treatment method used. However, hypervascular tumors may have excessive operative blood loss if the tumors are divided. We encountered a case of cauda equina hemangioblastoma with extraordinary blood supply, which was treated with preoperative embolization. A 49-year-old woman with von Hippel-Lindau disease who had undergone multiple surgeries for intracranial/extracranial hemangioblastomas had lumbago and leg pain. Magnetic resonance images revealed intradural spinal tumors at the L4-S1 vertebral level, with remarkable gadolinium enhancement. The patient was referred to our hospital, after a plan of total resection had been abandoned elsewhere because of the high flow feeders and high pressure of the tumors. Preoperative embolization was performed with consequent disappearance of the arterial blood supply to the tumor. Two days later, the tumor was resected subtotally with reduced tension and a little blood loss. The patient’s symptoms resolved soon after surgery. Selective preoperative embolization for a spinal hemangioblastoma with a rich blood supply is a valid option as an adjuvant to the complete surgical resection of a tumor.
