Eight children with hydrocephalus showed signs of posterior fossa tonsillar impaction despite arrest of the hydrocephalus and patency of their CSF shunts. Contrast studies performed because of their clinical deterioration demonstrated cerebellar tonsillar herniation, and at posterior fossa decompression, this was confirmed in all cases. Improvement followed decompression. The pathogenesis of a state of cephalocranial disproportion following successful treatment of hydrocephalus resulting in symptomatic tonsillar herniation, is discussed.
八名脑积水患儿尽管脑积水已得到控制且脑脊液分流管通畅，但仍出现后颅窝扁桃体嵌顿的迹象。因其临床病情恶化而进行的造影检查显示有小脑扁桃体疝，而后颅窝减压手术时，所有病例均证实了这一点。减压后病情有所改善。本文讨论了脑积水成功治疗后导致有症状的扁桃体疝的头颅比例失调状态的发病机制。
