Acute hydrocephalus and death one month after non-surgical treatment for acute cerebellar hemorrhage. Case report.

Acute cerebellar hemorrhages, treated medically with subsequent complete recovery, have been designated "benign cerebellar hemorrhages." Ordinarily, acute cerebellar hemorrhage does require early surgical intervention and reported surgical mortality is relatively low (17%) in awake patients with this lesion. Clinical studies have shown that, after a period of approximately 2 weeks, the predicted mortality for this disorder becomes less than the operative mortality, and patients are then expected to recover. The author reports a case, with serial computerized tomography scanning, in which deterioration and death occurred 4 weeks after acute cerebellar hemorrhage. It is concluded that surgical intervention should be considered early in the clinical course of all cases of acute cerebellar hemorrhage.
