The relation of intracranial air to C.S.F. rhinorrhoea in our four cases, one intracerebral and the others intracerebral-ventricular pneumocephalus, were investigated on their clinical course, operative findings and RI-cisternographic findings. In the occurrence of the pneumocephalus, it seemed important for the damaged brain to herniate into the defect of the bone and dura matar. Clinically in the stage of an intracerebral pneumocephalus, the C.S.F. rhinorrhoea was not recognized as a rule. And next stage, the sudden effusions of C.S.F. appeared when the intracerebral pneumocephalus developed to the intracerebral-ventricular pneumocephalus.
对我们的4例患者（1例为脑内积气，其他为脑室内积气），从其临床病程、手术所见及放射性核素脑池造影结果等方面，研究了颅内积气与脑脊液鼻漏之间的关系。在积气的发生过程中，受损脑组织疝入颅骨和硬脑膜缺损处似乎很重要。临床上，在脑内积气阶段，通常不会发现脑脊液鼻漏。而在下一阶段，当脑内积气发展为脑室内积气时，会突然出现脑脊液渗漏。
