title: Supratentorial craniotomy complicated by an homolateral remote cerebellar hemorrhage and a controlateral perisylvian infarction: case report.
abstract: The authors present the case of a 49-year-old male patient with a right remote cerebellar hemorrhage and left perisylvian venous infarction complicating a right supratentorial craniotomy for temporal meningomia resection. These two events may result from a functional stenosis (due to perioperative brainstem sag) of the junction between the vein of Galen and the straight sinus. Remote cerebellar hemorrhage could then be explained by infarction in the territory of cerebellar veins emptying in the vein of Galen, and the left perisylvian infarction could be caused by venous infarction in the territory of a dominant superficial sylvian vein emptying in the basal vein. This hypothesis could shed light on the pathophysiology of remote cerebellar hemorrhage.
