Saggital view of a human brain from an MRI (magnetic resonance image) to illustrate the location of the cerebellopontine angle.

The cerebellopontine angle (CPA) is formed at the junction of the cerebellum, pons, and medulla; the most common tumor found in this location is the acoustic neuroma. Meningiomas are the second most common tumor found in this location.
