title: Subarachnoid Hemorrhage due to Spinal Cord Schwannoma Presenting Findings Mimicking Meningitis.
abstract: BACKGROUND
  Subarachnoid hemorrhage (SAH) of spinal origin is uncommon in clinical practice, and spinal schwannomas associated with SAH are even more rarely reported. We report an unusual case of spinal SAH mimicking meningitis with normal brain computed tomography (CT)/magnetic resonance imaging (MRI) and negative CT angiography. Cerebrospinal fluid examination results were consistent with the manifestation of SAH. Spinal MRI performed subsequently showed an intradural extramedullary mass. The patient received surgery and was finally diagnosed with spinal cord schwannoma.
  
  
  METHODS
  A retrospective chart review of the patient was performed.
  
  
  RESULTS
  We describe a case of SAH due to spinal cord schwannoma. Our case highlights the importance of careful history taking and complete evaluation.
  
  
  CONCLUSIONS
  We emphasize that spinal causes should always be ruled out in patients with angionegative SAH and that schwannoma should be considered in the differential diagnosis of SAH etiologies even though rare.
