Since Dandy's description in 1919 on the roent-genographical examination of the central nervous system by air injection through spinal subarachnoid space, pneumoencephalography has been used ex-tensively and this procedure has still diagnostic value in the field of neurology and neurosurgery in spite of present widespread appliation of cerebral angiography.

Many articles had published by various authors on the pneumoencephalography. The majority had dis-ccussed on development of the new techniques, complication and various pathological findings and very few papers on the cause of failure to fill the ventricular system in cases which has no pathological obstruction of cerebrospinal fluid pathway.

The purpose of this paper is to know the cause of unfilling of ventricular system in normal cases and to procedure to get ventricular shadow in such cases.

The 83 cases out of 909 cases which had done the pneumoencephalography in Neurosurgical department of Sapporo Medical College Hospital during past 10 years are submitted to this study as cases of non-filling of ventricular system. 83 cases were able to classify into six groups as following based on the intracranial location of air.

1st group: No air is visible intracranially.

2nd group: Localized air collection in Cisterna Magna.

3rd group: The air is visible mainly in basal ara-chnoidal cisterna.

4th group: The air is visible in dorsal arachnoidal cisterna of brain stem.

5th group: Combined and complicated cases of above 3rd and 4th groups.

6th egroup: Subdural air collection.

From the anatomical and hydrodynamic stand point the cause of unfilling of ventricular system was disccussed in each groups and procedure to get the ventricular filling in each group had also described.
