Figures 61A,61B and 61C: Axial noncontrast head CT images from inferior to superior demonstrate diffuse subarachnoid hemorrhage in the suprasellar, interpeduncular, and ambient cisterns with extension laterally into the Sylvian fissures and superiorly along the interhemispheric fissure. There is also a parenchymal hematoma in the right frontal lobe (most apparent in Figs. 61A and 61B) as well as hemorrhage in both lateral ventricles (Fig. 61C).
