Cerebellar hemorrhage after supratentorial surgery for treatment of epilepsy: report of two cases.

Hemorrhage occurring at regions remote from the operative site is an infrequent complication. Although the mechanism remains unclear, previous reports implicate over drainage of cerebrospinal fluid as the predominant mechanism. The authors report two cases of cerebellar hemorrhage after supratentorial surgery. Two young patients underwent left hemispherectomy and fronto-temporal resection for the treatment of refractory hemispheric and multiregional epilepsy. The hemorrhage manifested early in the immediate postoperative period as delayed awakening. The diagnosis was established by computed tomography. Treatment consisted in external ventricular drainage in case 1 and conservative treatment in case 2. Both patients recovered without major neurological deficits. Early detection and awareness of this complication may help to avoid further neurological morbidity and mortality.
