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 subarachnoid cisterns, or basal cisterns, are compartments within the subarachnoid space where the pia mater and arachnoid membrane are not in close approximation and cerebrospinal fluid (CSF) forms pools or cisterns (Latin: "box"). As they are interconnected, their patency is essential for CSF circulation.
The quadrigeminal cistern (also known as superior cistern or cistern of the great cerebral vein) is one of the CSF -filled subarachnoid cisterns. Boundaries. The boundaries of the quadrigeminal cistern are as follows 2: anterior: quadrigeminal plate of the midbrain (or colliculi)
The quadrigeminal cistern is also known as the superior cistern, ambient cistern or cistern of the great cerebral vein. The precise location is between the splenium of the corpus callosum and the upper surface of the cerebellum , i.e. dorsal to the midbrain .
The quadrigeminal cistern is a dilated space within the subarachnoid region located behind the superior and inferior colliculi of the mid-brain. It is surrounded at the front by the colliculi, known as the quadrigeminal plate, and the pineal gland.
The quadrigeminal cistern lies under the corpus callosum splenium, behind the pineal gland and tectal plate. It connects with the ambient cisterns laterally and the superior cerebellar cistern inferiorly. The quadrigeminal cistern contains the pineal gland, trochlear nerves, P3 PCA segments, proximal choroidal arteries, and vein of Galen.
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.
The quadrigeminal cistern is the cistern of the pineal region. It contains the P4 segment of the PCA and the distal SCA, the medial posterior choroidal artery, the trochlear nerve, and the galenic venous system.
The great cerebral vein traverses the quadrigeminal cistern of the brain, which is why this area is sometimes referred to as Galen's cistern. Within the cistern, the vein takes a posterior course, curving around the inferior aspect of the splenium of corpus callosum and reaching its posterior side.
Quadrigeminal plate and cistern. Prominent midbrain eminences including the superior and inferior colliculi medially and the middle cerebellar peduncle just below the trochlear nerve.
