Cases of Subarachnoid Hemorrhage

CT of cerebral edema and subarachnoid hemorrhage
Axial CT without contrast of the brain shows diffuse low density through the bilateral cerebral hemispheres (anteriorly) with a normal density cerebellum (posteriorly) that appears relatively hyperdense when compared to the cerebral density. Subarachnoid hemorrhage was also seen bilaterally in the basal cisterns.
