[Teratoma in the cerebellar hemisphere of an infant].
關鍵詞
抽象
We report here a 4-month-old male infant with a cerebellar teratoma. After vomiting for 5 days, he had a tonic-clonic seizure on the left showing secondary generalization. Neuroimaging studies showed severe hydrocephalus and a large tumor in the left cerebellar hemisphere, which showed calcification. Postictal scalp electroencephalogram showed right hemispheric spikes and spike-waves. He underwent an emergency operation and had the tumor totally removed. Histological diagnosis of the tumor was immature teratoma. Intracranial teratomas have a predilection for supratentorial and midline sites. They are the most common in the neonatal period. We presented a very rare case of teratoma in the cerebellar hemisphere of an infant.
