title: Spinal intradural extramedullary mature cystic teratoma in an adult: A rare tumor with review of literature.
abstract: BACKGROUND
  Spinal intradural extramedullary teratoma is a rare condition, more common in children than in adults often with a history of spinal dysraphism.
  
  
  METHODS
  We reviewed the literature and Pubmed advanced search showed nine results of intradural extramedullary teratoma in adults which included five independent case reports and three cases in a case series. We reported a rare case of intradural extramedullary teratoma in an adult located opposite L4 vertebra with neither spinal dysraphism nor any history of the prior spinal procedure.
  
  
  RESULTS
  The occurrence of teratomas in the spine is extremely rare. Further, spinal intradural extramedullary teratoma is more common in children but a rare entity in adults.
  
  
  CONCLUSIONS
  Although uncommon, spinal cord neoplasm should be considered in the differential diagnosis of backache or radicular pain associated with neurological deficits even in absence of spinal dysraphism or any spinal procedure.
