A case of tension pneumocephalus following suboccipital craniectomy and ventriculoperitoneal (VP) shunt surgery for obstructive hydrocephalus due to the presence of a cerebellopontine (CP) angle tumor is reported. The air entries were found on both sides of the frontal skull base. The formation of the fistula may have been either due to congenital bony defects or chronically elevated intracranial pressure. Iopamidol computed tomographic (CT) cisternogram was one of the diagnostic tools. Direct surgical repair of those bony-dural defects was mandatory in the prevention of the recurrence of the pneumocephalus.
本文报道了一例因桥小脑角肿瘤导致梗阻性脑积水，在枕下颅骨切除及脑室腹腔分流术后发生张力性气颅的病例。气颅出现在额骨基底两侧。瘘管的形成可能是由于先天性骨缺损或长期颅内压升高。碘帕醇计算机断层扫描（CT）脑池造影是诊断工具之一。直接手术修复这些骨-硬膜缺损对于预防气颅复发至关重要。
