RESUMO
The clinical and radiographic findings of 68 children and adolescents with nontraumatic intraparenchymal brain hemorrhage were analyzed retrospectively. There were 43 boys and 25 girls, and the average age was 7.1 years (range, 3 months to 18 years). The most common presenting symptom was a combination of headache or vomiting (40 cases, or 58.8%). Hemiparesis was the major presenting sign in 11 (16.2%) of the children, seizures occurred in 25 (36.8%) patients, and 6 (8.8%) children were irritable. Only 2 (2.9%) children were comatose at presentation. One or more risk factors for hemorrhage were found in 61 (89.7%) of 68 children. A third (23 cases, or 33.8%) had an arteriovenous malformation or fistula; altogether 29 (42.6%) children had some type of congenital vascular anomaly. Hematologic or coagulation disorders were present in 22 (32.4%) patients, and 9 (13.2%) patients had brain tumors. Hemorrhage could not be attributed to systemic hypertension in any child. The likelihood of establishing the cause of bleeding was greater when evaluation included cerebral angiography (97.3% versus 80.4% without angiography). Half (34 cases, or 50.0%) of the patients regained normal neurologic function. Six (8.8%) patients died, either directly or partly as a consequence of the hemorrhage. The remaining patients had various neurologic sequelae, including 17 (25.0%) with hemiparesis, 5 (7.4%) with aphasia, 7 (10.3%) with epileptic seizures, and 3 (4.4%) with hydrocephalus. More detailed follow-up studies are needed to obtain more information about the frequency of cognitive sequelae.
