A Healed Incomplete Rupture of a Small Artery Jutting to the Lateral Ventricle: A Possible Cause of Primary Intraventricular Hemorrhage

Primary intraventricular hemorrhage (PIVH) is a rare type of non-traumatic intracerebral hemorrhage confined to the ventricles, without any substantial parenchymal or subarachnoid bleeding. The origins of PIVH include arteriovenous malformation, aneurysm in the choroid plexus, brain tumor, and Moyamoya disease, although in many PIVH patients (25-48 %) the cause remains unknown [1]. With the recent increase in the use of postmortem imaging, forensic pathologists may encounter PIVH cases. In cases with a traumatic event, PIVH must be differentiated from a traumatic hemorrhage.
