Intradural extramedullary cavernous hemangioma of the cervicothoracic junction: A case report and review of the literature

Background: Intradural extramedullary cavernous hemangiomas of the spine are rare, benign lesions with only 40 published cases to date. Case description: The authors report a rare case of a histologically diagnosed intradural extramedullary cavernous hemangioma of the spine involving the cervicothoracic junction and causing sudden gait disturbances and urinary retention in a 24-year-old male. Gross total tumor removal allowed complete spinal decompression and sensible improvement of the clinical condition with no evidence of tumor relapse at 12-month follow-up examination. Conclusion: More frequently found in the lower thoracic and lumbar spine, these tumors often cause subtle clinical manifestations including sensory and motor dysfunction secondary to nerve root compression; nonetheless, occasional cases of rapidly progressive worsening of the neurological condition with evidence of myelopathy and autonomic dysfunction have been described. In such cases, urgent surgical resection is crucial since the degree of neurological impairment and the time spanned from the onset of the symptoms are paramount for a good recovery.
