The quadrigeminal cistern [1] (also cistern of great cerebral vein, [1] vein of Galen cistern, [2] superior cistern, [2] [3] Bichat's canal, [3] or peripineal cistern [2]) is a subarachnoid cistern situated between splenium of corpus callosum, and the superior surface of the cerebellum.
Quadrigeminal cistern - It is situated dorsal to the midbrain. Thin, sheet-like extensions of the superior cistern that extend laterally about the midbrain, connecting it to the interpeduncular cistern. Ambient cistern may also refer to the combination of these extensions and the superior cistern.
Each ambient cistern extends anterolaterally around the mesencephalon to become continuous rostrally/anteriorly with the interpeduncular cistern. [2] Each ambient cistern is continuous dorsally/posteriorly with the quadrigeminal cistern; [3] [4] inversely, each ambient cistern is an anterolateral extension of the quadrigeminal cistern on either side [2] (some sources define the quadrigeminal ...
It runs posteriorly along the cerebral peduncle passing the crural and ambient cisterns. It then gives off branches to supply quadrigeminal plate and the adjacent structures in the midbrain. The origin of this artery is proximal to the origin of medial and lateral posterior choroidal branch of the posterior cerebral artery.
It is located in the quadrigeminal cistern. [1] ... Of the endocrine organs, the function of the pineal gland was the last to be discovered. [84] Society and culture
Radiographically, downward herniation is characterized by obliteration of the suprasellar cistern from temporal lobe herniation into the tentorial hiatus with associated compression on the cerebral peduncles. Upwards herniation, on the other hand, can be radiographically characterized by obliteration of the quadrigeminal cistern.
