The suprasellar cistern (also known as pentagon of basal cisterns) is a cerebrospinal-fluid filled space located above the sella turcica, under the hypothalamus. It contains the optic chiasma, the infundiblarinfundibular stalk and the polygone of Willis. It had the shape of a pentagon at the level of the optic chiasma, and the shape of a six-point star at the level of cerebral peduncles, frequently likened to a Jewish star

It is an important intra-cranial cistern to review on MRI and CT, since it can be obliterated in uncal herniation and in cases of severe intra-cranial hypertension. It can also be filled with blood from subarachnoid hemorrhage.
