title: Internal carotid false aneurysm after thermocoagulation of the gasserian ganglion.
abstract: OBJECTIVE
  To identify petrous internal carotid bleeding aneurysm as a complication of gasserian ganglion thermocoagulation.
  
  
  METHODS
  A single case presenting with epistaxis and otorrhagia 1 month after gasserian ganglion thermocoagulation in the treatment of refractory trigeminal neuralgia.
  
  
  METHODS
  Gasserian ganglion thermocoagulation, computed tomographic scan, and angiocomputed tomographic scan revealing petrous internal carotid ruptured aneurysm and internal carotid embolization.
  
  
  METHODS
  Radiologic diagnosis of the vascular injury after gasserian ganglion thermocoagulation.
  
  
  RESULTS
  Radiologic identification of ruptured internal carotid artery as the cause of simultaneous epistaxis and otorrhagia.
  
  
  CONCLUSIONS
  Gasserian ganglion thermocoagulation may cause aneurysm and rupture of the petrous portion of the internal carotid artery.
