One involves blood directly entering the ventricles via the ventricle wall, similar to IVH caused by the rupture of an anterior communicating artery aneurysm through the lamina terminalis. The second mechanism involves large amounts of aneurysmal SAH regurgitating into the fourth ventricle via the foramina of Luschka.

The anteroventral wall of third ventricle (AV3V) that includes the organum vasculosum lamina terminalis (OVLT), the ventral portion of the MnPO, the preoptic periventricular nucleus, and the more medial aspects of the medial preoptic nucleus is an important region that is involved in body fluid and cardiovascular regulation [25, 32, 37].
