title: False-positive magnetic resonance imaging in the diagnosis of vestibular schwannoma.
abstract: OBJECTIVE
  To describe the case of a true false-positive finding on magnetic resonance imaging, mimicking a vestibular schwannoma, and review the pertinent literature.
  
  
  METHODS
  The case of a single patient with a suspicion of a vestibular schwannoma.
  
  
  METHODS
  A middle fossa craniotomy was performed for resection of the presumed schwannoma.
  
  
  METHODS
  Intraoperative findings and postoperative magnetic resonance imaging (MRI).
  
  
  RESULTS
  : Intraoperative findings and a postoperative MRI confirm the absence of a neoplasm.
  
  
  CONCLUSIONS
  False-positive findings on MRI, though rare, do occur. The clinician should have a high index of suspicion and consider reimaging in some cases.
