Interpeduncular cistern

The interpeduncular cistern (or basal cistern) is one of the subarachnoid cisterns. It is a wide CSF- filled cavity between the two temporal lobes anteriorly and encloses the cerebral peduncles as well as structures contained within the interpeduncular fossa. It is continuous anteriorly with the suprasellar cistern.

It contains the oculomotor nerve (CN III) and the terminal basilar artery (from the circle of Willis) and its branches. It is continuous with the pontine cistern inferiorly and the remainder of the subarachnoid space.
