Intraventricular hemorrhage (IVH), also known as intraventricular bleeding, is a bleeding into the brain's ventricular system, where the cerebrospinal fluid is produced and circulates through towards the subarachnoid space. It can result from physical trauma or from hemorrhagic stroke.

30% of intraventricular hemorrhage (IVH) are primary, confined to the ventricular system and typically caused by intraventricular trauma, aneurysm, vascular malformations, or tumors, particularly of the choroid plexus.^[2] However 70% of IVH are secondary in nature, resulting from an expansion of an existing intraparenchymal or subarachnoid hemorrhage.^[2] Intraventricular hemorrhage has been found to occur in 35% of moderate to severe traumatic brain injuries.^[3] Thus the hemorrhage usually does not occur without extensive associated damage, and so the outcome is rarely good.^[4][5]
