title: Hemangioendothelioma of the spinal cord with intramedullary extension.
abstract: OBJECTIVE
  Hemangioendotheliomas (HE) are vascular neoplasms that rarely involve the neuraxis. We report a rare case in the literature of intradural HE of the spinal cord with intramedullary extension.
  
  
  METHODS
  A 41-year-old gentleman presented with low back pain, numbness and urinary retention. Imaging revealed a spinal tumor causing complete blockage at the level of T12. The tumor was resected and postoperative radiotherapy was delivered for residual disease. No disease was seen on MRI after 48 months of clinical and radiological follow-up.
  
  
  CONCLUSIONS
  Complete excision of HE is the treatment of choice. Radiotherapy may play a role in the management of this lesion.
