Six alcoholic patients developed extensive cerebral hemispheric hemorrhages with both intraventricular and subarachnoid blood.All patients had evidence of liver damage,low platelet counts,and abnormal prothrombin and partial thromboplastin times.Four patients presented with seizures;in two of the four,these seizures were initially diagnosed as alcohol withdrawal seizures.Four patients were comatose with lateralizing neurologic deficit;two patients were comatose without lateralizing neurologic deficit,suggesting a metabolic encephalopathy.In one patient there was delayed neurologic deterioration.In all six patients,computed tomography showed large diffuse cerebral hemispheric hemorrhages,prominent intraventricular blood,and breakthrough into the subarachnoid spaces,which was confirmed by necropsy findings.There was marked mass effect but minimal surrounding edema.All six patients died.In three,autopsy showed no evidence of aneurysm,vascular malformation,neoplasm,or amyloid angiopathy and no arteriolar hypertensive changes. |
