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]

The cistern communicates superiorly with the chiasmatic cistern, and inferiorly with the pontine cistern.^[3] The chiasmatic cistern, cistern of lamina terminalis, and supracallosal cistern are all extensions of the interpeduncular cistern.^[1]
