Pontine cistern

The pontine cistern (also pontocerebellar cistern, or prepontine cistern[1]) is a subarachnoid cistern in the interval between ventral aspect of the pons, and the clivus. It contains the basilar artery.[2]: 478  The lateral aperture opens into the pontine cistern just posterior to the cranial nerve VIII.[2]: 483

Anatomy

The pontine cistern is situated at the lateral aspects of the pons at its junction with the cerebellum. It may be subdivided into superior and inferior portions.[1]

It is continuous behind with the subarachnoid space of the spinal cord, and with the cisterna magna, and in front of the pons with the interpeduncular cistern.
