Cerebellopontine angle cistern

The cerebellopontine angle (CPA) cistern is situated in the lateral angle between the cerebellum and the pons.

superior: tentorium cerebelli

posterior: anterior surface of cerebellum

inferior: lower cranial nerves

anterior: cerebellar hemisphere

anterolateral: posterior surface petrous temporal bone

medial: pons

It contains:

The seventh (VII) and eighth (VIII) cranial nerves.

The anteroinferior cerebellar artery (AICA).

The fifth (V) cranial nerve and the petrosal vein.

The volumetric parameters of the CPA cistern are a marker for understanding the pathogenesis of TN and useful for predicting the recurrence after MVD. The Cistern Deviation Index might contribute to deciding the surgical approach.
