Crural cisterns, also known as cisterna cruralis, are paired cerebrospinal fluid-filled subarachnoid cisterns located at the level of the cerebral peduncles between the uncus and the optic tract 1.
Boundaries
The boundaries of the crural cisterns are 2:
ventral: communicates with the oculomotor and interpeduncular cisterns
dorsal: communicates with the ambient and Sylvian cisterns
Contents
The crural cisterns contain the anterior choroidal and medial posterior chorodial arteries and the basal vein of Rosenthal 2.
