因血管畸形破裂造成的脑内和脑室内出血，此种血管病变(组织学上称为动静脉畸形--AVM)引起的出血可以发生在脑内或者渗入脑室或蛛网膜下隙。
The intraventricular and intracerebral hemorrhage seen here was due to a ruptured vascular malformation. The hemorrhage from such a lesion (which is most often histologically an arteriovenous malformation--AVM) can be intracerebral or extend into ventricles or subarachnoid space.
