title: Intracerebral hemorrhage caused by transmural dissection of the anterior cerebral artery.
abstract: OBJECTIVE
  Spontaneous dissection of the intracranial carotid artery or its main branches is an unusual condition.
  
  
  METHODS
  A 72-year-old hypertensive woman after an intense nuchal rigidity showed a subarachnoid hemorrhage and an interhemispheric hematoma by computed tomography. The neuropathological study revealed a transmural dissection of the pericallosal artery.
  
  
  CONCLUSIONS
  The authors suggest that the dissection origin is an atheromatous plaque that bleeds, producing a dissection plane from the lumen to the adventitial artery.
