Abstract
Two infants were reported with intracerebellar hemorrhage due to rupture of angiomatous malformations in the cererbellum.
Case 1. A 2-month-old girl with vomiting and disturbance of consciousness. A CT scan revealed the left intracerebellar hemorrhage, and an angiogram revealed small arteriovenous malformations in the left cerebellar hemisphere. The hematoma was resected immediately, and the postoperative course was favorable.
Case 2. A 2-year-old boy with vomiting and gait disturbance. Intracerebellar hemorrhage was suspected by a CT scan. Six days later he rapidly began to lose consciousness. A CT scan revealed recurrence of the hemorrhage, but an angiogram revealed no abnormal blood vessels. The hematoma was resected because of acute disturbance of consciousness. Angiomatous malformations were found by the histological examination of the wall of the hematoma. The postoperative course was favorable.
There have been only a few reports on intracerebellar hemorrhage due to angiomatous malformation in infants. Even if angiomatous malformation was not revealed by preoperative angiography, it was necessary to examine the wall of the hematoma carefully during the operation. The results of operations for intracerebellar hemorrhage in infants ware more favorable than those in adults. Even if the patient showed severe neurological symptoms preoperatively, an operation should be performed.
