title: Fou rire prodromique heralding a left internal carotid artery occlusion.
abstract: BACKGROUND
  Four rire prodromique, described as pathological laughter preceding the onset of an apoplectic attack, is a rare phenomenon.
  
  
  METHODS
  A 61-year-old man manifested pathological laughter before a sudden right hemiplegia. MRI showed a left lenticular and caudate nucleus infarct with involvement of the external capsule and prerolandic area. MRA revealed a left internal carotid and middle cerebral artery occlusion.
  
  
  CONCLUSIONS
  The clinicoanatomic correlates of this phenomenon are discussed.
