The suprasellar cistern (also known asthe chiasmatic cistern or pentagon of basal cisterns) is one of the cerebrospinal fluid-filled subarachnoid cisterns.
Gross anatomy
Location
The suprasellar cistern is located above the sella turcica, under the hypothalamus and between the uncus of the temporal lobes. It has roughly the shape of a pentagon at the level of the optic chiasma, and of a six-point star at the level of cerebral peduncles.
Contents
It contains the proximal part of the Sylvian fissure (sometimes separately termed the Sylvian cistern), the optic chiasm, the infundibular stalk and the cerebrovascular circle of Willis.
Relations
It is continuous posteriorly with the interpeduncular cistern.
