RESUMO
OBJECTIVE: To discuss the clinical features, treatment, and prognosis of supratentorial cavernous angiomas in children. METHODS: The clinical data of 25 pediatric patients with supratentorial cavernous angioma, 17 boys and 6 girls, aged 9.6 (1-15), were reviewed retrospectively, and the relationship between the duration of epilepsy before surgery and prognosis was analyzed. RESULTS: The 14 patients with preoperative seizures underwent surgery. All (8/8) of the patients suffering from preoperative seizures with an history of less than one year were seizure free after operation, while only half (3/6) of the patients with an history suffering from preoperative seizures with an history of more than one year were seizure free after operation. Ten of the 11 patients with hemorrhage and hemorrhage-related neurological symptoms as the initial symptoms underwent surgery, and no symptoms of re-bleeding and seizure occurred postoperatively. CONCLUSION: Craniotomy for lesionectomy results in good seizure control and re-bleeding avoidance. Better results with regard to seizure control are associated with shorter duration of symptoms before surgery.
