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.
Cerebellopontine angle cistern. It is situated at the cerebellopontine angle – the lateral angle between the cerebellum and the pons. It contains: The seventh (VII) and eighth (VIII) cranial nerves; The anteroinferior cerebellar artery (AICA) The fifth (V) cranial nerve and the petrosal vein; Quadrigeminal cistern - It is situated dorsal to ...
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 ...
The cisterna magna (posterior cerebellomedullary cistern, [1] or cerebellomedullary cistern [2] [3]) is the largest of the subarachnoid cisterns.It occupies the space created by the angle between the caudal/inferior surface of the cerebellum, and the dorsal/posterior surface of the medulla oblongata (it is created by the arachnoidea that bridges this angle [3]).
Absence of the great cerebral vein is a congenital disorder.The deep cerebral veins of the brain normally drain through the great cerebral vein. In its absence, the veins from the diencephalon and the basal ganglia drain laterally into the transverse sinus instead of conjoining in the midline through the Galenic drainage system. [8]
The interpeduncular cistern (or basal cistern [1]) is the subarachnoid cistern situated between the dorsum sellae (anteriorly) [2] and the two cerebral peduncles [1] [3] [2] at the front of the midbrain. [3] Its roof is represented by the floor of the third ventricle (i.e. posterior perforated substance, and the two mammillary bodies).

Brain anatomy – forebrain, midbrain, hindbrain. The cerebral peduncles each form a lobe ventrally of the tegmentum, on either side of the midline. Beyond the midbrain, between the lobes, is the interpeduncular fossa, which is a cistern filled with cerebrospinal fluid [citation needed]. The majority of each lobe constitutes the cerebral crus.
