Thirty-one cases of acute posterior fossa infarcts are reported. CT evidence of obliterated posterior fossa cisterns and hydrocephalus indicates a grave prognosis due to brainstem compression. Progressive obliteration of posterior fossa cisterns may be used as an indicator for surgical decompression. Patients with intact posterior fossa cisterns had good recoveries without surgical treatment. CT can be used to diagnose the very early phase of an acute posterior fossa infarct and has prognostic value in predicting the outcome.
报告了31例急性后颅窝梗死病例。后颅窝脑池闭塞和脑积水的CT证据表明，由于脑干受压，预后严重。后颅窝脑池的进行性闭塞可作为手术减压的指标。后颅窝脑池完整的患者未经手术治疗也恢复良好。CT可用于诊断急性后颅窝梗死的极早期阶段，对预测预后具有价值。
