Radiographs of the brain
Lateral pneumoencephalogram
Air was injected into the lumbar subarachnoid space of this subject, a 1 year old child. The gas has entered the subarachnoid spaces surrounding the brain. The major subarachnoid cisterns are filled and, in addition, the sulci of the cerebral hemispheres in many places contain enough gas to render them visible.
