Interpeduncular cistern
The interpeduncular cistern (or basal cistern[2]) is the subarachnoid cistern situated between the dorsum sellae (anteriorly)[3]: 440 and the two cerebral peduncles[2][4][3]: 440 of the mesencephalon (midbrain).[4] 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.[3]: 440 Anteriorly, it extends to the optic chiasm.[2]

The cistern communicates superiorly with the chiasmatic cistern, and inferiorly with the pontine cistern.[4] The chiasmatic cistern, cistern of lamina terminalis, and supracallosal cistern are extension of the interpeduncular cistern.[2]
