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). Its floor is formed by the arachnoid membrane extending between the temporal lobes of either side.[2] Anteriorly, it extends to the optic chiasm.[1]
