Interpeduncular cistern. It is situated at the base of the brain, between the two cerebral peduncles of midbrain and dorsum sellae and continuous below with the pontine cistern and superiorly with the chiasmatic cistern. It contains: The optic chiasm; The bifurcation of the basilar artery; Peduncular segments of the posterior cerebral arteries ...
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]).
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).
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.
The angle formed in turn creates a subarachnoid cistern, the cerebellopontine angle cistern. The pia mater follows the outline of the fissure and the arachnoid mater continues across the divide so that the subarachnoid space is dilated at this area, forming the cerebellopontine angle cistern.

Endoscopic third ventriculostomy (ETV) is a surgical procedure for treatment of hydrocephalus in which an opening is created in the floor of the third ventricle using an endoscope placed within the ventricular system through a burr hole. This allows the cerebrospinal fluid to flow directly to the basal cisterns, bypassing the
The cistern of lamina terminalis is one of the subarachnoid cisterns. It is situated (depending upon the source) either superior to the lamina terminalis, [1] or rostral/anterior to the lamina terminalis and anterior commissure between the two frontal lobes of the cerebrum. [2] It is situated rostral/anterior to the third ventricle. [3]
The cerebellopontine cistern [2] (also pontocerebellar cistern, [1] cerebellopontine angle cistern, or angle cistern [2]) is a paired subarachnoid cistern at the cerebellopontine angle, an angle created between the cerebellum and the pons on either side. Each cerebellopontine cistern is continuous anteromedially with the prepontine cistern. [2]
