The authors proposed that exposure of the brain to atmospheric pressure allowed for the paradoxical herniation (see Fig. In terminal stages with global infarction, there will be a white cerebellar sign as well. GCS. The proposed mechanism of paradoxical herniation may be that atmospheric pressure and the brain gravity overwhelm over the natural buoyancy that CSF provided to the brain; the brain has become collapsed after the DC, and the brain stem has get compressed [3, 4]. .
