title: Dermoid tumor of the lateral wall of the cavernous sinus.
abstract: BACKGROUND
  Congenital intracranial dermoid tumors are very rare. The location of these dermoid lesions in the cavernous sinus and the complexity of the operative procedure for these lesions have been noted by several authors. Dermoid tumors originating in the cavernous sinus are usually interdural, and thus blurred vision is an uncommon presentation.
  
  
  METHODS
  Herein we report the first incidental case of a cavernous sinus dermoid cyst in a 21-year-old woman.
  
  
  CONCLUSIONS
  A literature review was done and the possible treatments and approaches for this lesion are discussed. We consider that surgical treatment is indicated in most incidental cavernous sinus dermoid lesions due to the possible symptoms related to compression or rupture leading to chemical meningitis.
