Multiple sporadic spinal hemangioblastoma at the filum terminale and cervicodorsal junction: A case report and review of literature

Hemangioblastomas are low-grade tumors that frequently occur in the posterior fossa. Only 1%–5% of these tumors occur in the spinal cord and there are a handful of cases of filum terminale hemangioblastomas described in the literature. Here, we present a case with two spinal hemangioblastomas at filum terminale and cervicodorsal junction of sporadic origin. A 28-year-old woman presented with low back pain radiating to right lower limb with weakness of both lower limbs and urinary incontinence. The findings of the examination revealed asymmetric quadriparesis with more weakness on the left side of the body. Magnetic resonance imaging revealed a cervicodorsal and lumbar T2 hyperintense lesion with flow voids. Imaging findings were suggestive of hemangioblastoma. En bloc excision of both the tumors was performed and the diagnosis was confirmed on histopathology. She had an uneventful postoperative course and complete neurological recovery at the final follow-up. Multiple sporadic spinal hemangioblastomas involving the filum terminale are a very rare entity. Complete surgical excision provides good relief of symptoms.
