Delayed Intracerebral Tension Pneumocephalus - Report of Two Cases -

遲發性張力氣腦-兩個病例報告-

摘要


有兩位頭部受傷之病患,被發現各於頭部受傷後之五個月及十二個月時,產生遲發性張力性的氣腦。 兩位病患之頭部X光攝影顯示出,於左側額葉處有一充滿氣體之大囊腫。 從額骨處做開顱術,經硬腦膜內做腦膜修復。手術中發現顱底篩骨篩板處有骨折併硬腦膜裂開,及充滿氣體之大腦囊腫。手術前變差之意識於手術後逐漸恢復。 電腦斷層可用於偵側氣體囊腫的位置,相關骨折處及對腦部所造成之張力性變化。

Two patients were found with delayed intracerebral tension pneumocephalus 5 and 12 months later, following head injury. Simple skull X-ray showed a large air-containing cyst in the left frontal lobe in both cases. Dural repairs were done through an intradural approach via single frontal craniotomy. Basal skull fracture with dural tear at cribriform plate of ethmoid bone and intracerebral cyst filled with air were found during operation. Their deteriorated consciousness became clear post-operatively. Plain computed tomography was a very useful instrument in determining the location of the gas collection, fracture site, and tension on the brain.
