A series of 96 cases with intraventricular hemorrhage diagnosed by computed tomography (CT scan) is described. The early conscious level, the causes, the site of ventricular hemorrhage and the final outcome are analyzed. Intraventricular hemorrhage is generally considered to be of grave prognostic significance. Hypertension and arterial aneurysm accounted for 73.9% of the cases. The overall mortality rate was 68.8%. All cases were admitted on Day 0 or 1, and more than half were classified neurologically as grade IV or V. CT scan reliably demonstrated the presence and distribution of blood within the ventricular system including the third and fourth ventricles. Surgical treatment was beneficial in only a small number of cases.
