Extensive subarachnoid hemorrhage (blood in the basal cisterns, sylvian fissures, interhemispheric fissure and few sulci). Well-defined hyperdense structure (likely a hematoma) measuring 2.3 x 2.4 x 2.3 cm in the anterior interhemispheric fissure raising the suspicion of ruptured anterior communicating artery aneurysm. No intraparenchymal or intraventricular hemorrhage, acute infarction or midline shift is seen. Mildly dilated lateral and third ventricles without any periventricular CSF leak.
