Suprasellar cistern

The suprasellar cistern (also known as pentagon of basal cisterns) is a cerebrospinal-fluid filled cistern located above the sella turcica, under the hypothalamus and between the uncus of the temporal lobes. It contains the optic chiasma, the infundibular stalk and the cerebrovascular circle of Willis. It has 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 the star of David. It is continuous posteriorly with the interpeduncular cistern.

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 intracranial hypertension. It can also be filled with blood from subarachnoid haemorrhage.
