Extradural thoracic nerve root hemangioblastoma approached by a combined posterior thoracic spine and video-assisted thoracoscopic surgery: A case report

BACKGROUND: Hemangioblastomas commonly occur in the posterior fossa and are typically attributed to sporadic or familial Von Hippel–Lindau disease. Spinal hemangioblastomas, found in 7–10% of patients, are usually located within the cord (i.e., intramedullary). Here, a 58-year-old male presented with a purely extradural hemangioblastoma involving a spinal root that was surgically excised. CASE DESCRIPTION: A 58-year-old male was admitted with a progressive paraparesis and incomplete sensory deficit. The magnetic resonance imaging documented a solid dumbbell-shaped lesion that extended through the left T3-T4 foramen resulting in nerve root and spinal cord compression. Following arterial embolization and lesion excision by both neurosurgeons and thoracic surgeons, the patient’s deficits improved. The postoperative computed tomography scan documented complete tumor removal, and the neuropathology revealed a hemangioblastoma. CONCLUSION: Here, we describe a 58-year-old male with a purely extradural thoracic foraminal T3-T4 dumbbell-shaped hemangioblastoma successfully treated by both embolization and surgical excision.
