Hemangioblatomas are low grade, highly vascular tumors usually associated with VHL syndrome and most commonly occurs in the cerebellum. They very rarely occur in the spinal nerve roots and an origin in the filum terminale is exceptionl. A 47 year old man presented with low back pain, paresthesias and stiffness of the both lower limbs. He also had urinary retention and constipation. MRI showed an enhancing mass at the L5 vertebral level with multiple dilated and tortuous vessels at both poles of the tumor. Digital subtraction angiogram showed the tumor to be supplied by the anterior spinal artery and dural branches of lumbar arteries. At surgery, a well-defined tumor with orange red hue was found to be arising from the filum terminale. The tumor was excised en bloc. Histopathological examination showed hemangioblastoma which was confirmed with immunohistochemistry. Clinical symptoms improved significantly after surgery. A sporadic hemangioblastoma arising from the filum terminale should be considered as a rare cause of back pain and sciatica. Total excision of the tumor usually cures the patient.
