Anatomical terms of neuroanatomy |
The cerebellopontine angle is a structure at the margin of the cerebellum and pons.
contents :
- facial N. (CN VII)
- vestibulocochlear (CN VIII)
- flocculus of the cerebellum
- lateral recess of the 4th ventricle
It is where vestibular schwannomas are usually found.
