title: Isolated trigeminal neuropathy due to trigeminal nerve root hemorrhage.
abstract: BACKGROUND
  Isolated trigeminal neuropathy is uncommon; causes include trauma, inflammation, or neoplasm.
  
  
  METHODS
  We report a patient who fell and struck his head during a myocardial infarction, was treated with streptokinase, and developed symptoms and signs of an isolated trigeminal sensory neuropathy.
  
  
  RESULTS
  Imaging showed hemorrhage in the trigeminal nerve root; follow-up imaging showed resolution of the hemorrhage, but no underlying structural lesion.
  
  
  CONCLUSIONS
  A combination of head trauma plus thrombolysis resulted in an isolated trigeminal neuropathy.
