Hydrocephalus after Subarachnoid Hemorrhage: Pathophysiology, Diagnosis, and Treatment

Figure 4

This picture shows a case of acute HCP induced by aneurysmal SAH, typically with an IVH. It happened as soon as the occurrence of SAH. (a) The CT scans above show widely hemorrhagic sulci and arachnoid cisterns with dilated lateral and third ventricles containing blood. (b), (c), and (d) Immediate CTA after admission locates the culprit aneurysm on the anterior communicating artery (marked by black arrows).
