The prepontine cistern lies between the upper clivus and the “belly” of the pons. It contains numerous important structures including the basilar artery, the anterior inferior cerebellar arteries (AICAs), and the trigeminal and abducens nerves (CN5 and CN6). The premedullary cistern is the inferior continuation of the prepontine cistern. It ...

The cisterna pontocerebellaris (also known as the prepontine cistern or the pontocerebellar cistern) is a rhomboid-shaped space encasing the pons (Figures 16A-16E), located at the pontocerebellar angle, and serves as an important surgical access landmark to …

The prepontine cistern is an expanded subarachnoid space that lies in front of the pons. The lateral apertures of Luschka emptu into the prepontine cistern from the 4th venrticle. Superiorly it is continuous with the interpeduncular cistern and inferiorly it continues into the prenedullary cistern and cisterna magna.

Inferiorly the premedullary cistern is continuous with the subarachnoid space around the spinal cord. This cistern contains the paired vertebral (VA) and anterior spinal arteries, as well as the paired hypoglossal nerves. It may also contain the origin of the PICA.
