Presented to the ED with confusion, after having fallen in his home. A CT head was performed to rule out an intracranial bleed. The CT showed massive intraparenchymal, subarachnoid, and intraventricular hemorrhage. The location of the intraparenchymal hemorrhage was suggestive of a ruptured pericallosal artery aneurysm, which a CTA showed to be the case.
Sadly, the patient died before any intervention could be attempted.
