Anatomy edit
The pontine cistern is situated ventrally/anteriorly to the pons,[1][2] in the interval between ventral aspect of the pons, and the clivus.[3]: 478
Contents edit
The cistern contains the origin of the abducens nerve (CN VI),[1][2] the basilar artery[2] and the origin of the basilar artery and of its branches,[1] and the anterior inferior cerebellar artery, and superior cerebellar artery.[1][2]
Relations edit
It is continuous inferiorly with the subarachnoid space of the spinal canal, posterolaterally with the cerebellopontine cistern of either side, and rostrally/anteriorly with the interpeduncular cistern.[1]
