The prepontine cistern, or pontine cistern is one of the subarachnoid cisterns situated ventral to the pons.[1] It contains the basilar artery.[2]: 478 Each lateral aperture opens into the pontine cistern just posterior to the cranial nerve VIII.[3][2]: 483
Anatomy
[edit]The pontine cistern is situated ventral to the pons,[1][3] in the interval between ventral aspect of the pons, and the clivus.[2]: 478
Contents
[edit]The cistern contains the origin of the abducens nerve (CN VI),[1][3] the basilar artery[3] and the origin of the basilar artery and of its branches,[1] and the anterior inferior cerebellar artery, and superior cerebellar artery.[1][3]
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]
