View Derek Smith's current disclosuresThe interpeduncular cistern is an unpaired CSF-filled subarachnoid cistern located between the cerebral peduncles.
It is partially bounded by the leaves of the Liliequist membrane, one of the arachnoid membranes, which separate it from its direct cranial and caudal relations1.
- superiorly the diencephalic leaf, separates this space from the suprasellar cistern above
- inferiorly the mesecephalic leaf, separates it from the prepontine cistern below
- laterally, the margin is the medial borders of the cerebral peduncles, therefore, this space communicates with the crural cisterns and ambient cisterns laterally
The interpeduncular cistern also has limiting borders.
- posteriorly it is the posterior perforated substance
- anteriorly it is the origin of the leaflets of the Liliequist membrane
This cistern contains a number of structures including the proximal portion of the oculomotor nerves (CN III), the distal basilar artery, the origin of the posterior cerebral arteries (and thalamoperforating arteries) as well as the origin of the superior cerebellar arteries. Depending on the posterior limit of the diencephalic membrane this space can also be said to communicate with the suprasellar cistern contents (the mammillary bodies) 4.

- subarachnoid hemorrhage - as the interpeduncular cistern is a dependent space in the supine position, small volume subarachnoid hemorrhage may be detected here
