Primary intraventricular hemorrhage (PIVH) is a rare type of stroke defined as bleeding within the ventricles of the brain with-out any associated parenchymal hemorrhage. Here, we reported two cases of sudden death due to PIVH. One of the patients was found deadunder a highway bridge without witnesses, and the other patient was hospitalized with hemorrhage in the ventricular system, as revealed by ahead computed tomography scan. In these two patients, autopsy and macroscopic examination only showed hemorrhages in the ventricular sys-tem without any traumatic brain injury or other intraparenchymal hemorrhage. The sources of bleeding for both patients were ultimately con-firmed as ruptured brain arteriovenous malformations located in the subventricular zone. We reported these cases to broaden our understandingof sudden death associated with PIVH, especially when caused by brain arteriovenous malformation. We also summarized the essential detailsof the diagnoses and available technical methods for PIVH cases.
