Abstract：
We report here a very rare case of spontaneous intraventricular tension pneumocephalus. This case concerns a 40-year-old patient with a medical history of a tumor of the pineal region and secondary hydrocephalus treated by multiple ventriculoperitoneal shunts. He presented in the emergency room because of unusual headaches, nausea, and visual loss. In addition, he reported slight rhinorrhea for a few weeks. The initial brain CT scan revealed a spontaneous intraventricular tension pneumocephalus. There was no history of recent head trauma and no sign of disconnection of the shunt system. A complementary radiological assessment included a thin-slice bone CT scan and a radioisotope cisternography that revealed an osseous defect and an isotope leakage at the junction between the tegmen tympani and the squamous part of the left temporal bone. A middle cranial fossa surgery was performed to repair the osteo-meningeal breach.
摘要：
我们在这里报告了非常罕见的自发性心室内张力性气颅病例。该病例涉及一名40岁的患者，该患者有松果体区肿瘤病史，并通过多脑室腹膜分流术治疗继发性脑积水。他因为不寻常的头痛出现在急诊室，恶心,和视觉损失。此外,他报告了几个星期的轻微鼻漏。最初的脑部CT扫描显示自发性脑室内张力性气血。没有近期头部外伤的病史，也没有分流系统断开的迹象。补充的放射学评估包括薄层骨CT扫描和放射性同位素池造影，该造影显示骨缺损和同位素渗漏在鼓膜和左颞骨鳞状部分之间的交界处。进行了中颅窝手术以修复骨膜破裂。
