Diffuse arachnoid hemorrhage, centered within the anterior interhemispheric fissure and bilateral sylvian and interhemispheric fissures, with blood products extending inferiorly into the basal cisterns and to a lesser degree the prepontine cistern. Blood products are also present in the lateral, third and fourth ventricles with dilated ventricles.
