[The relation of intracranial air to C.S.F. rhinorrhoea in the traumatic pneumocephalus (intracerebral and ventricular) (author's transl)].

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.
