The cerebellopontine angle syndrome

The cerebrospinal angle is the space between the cerebellum and the pons, which is filled with cerebrospinal fluid and is a very common site of vestibular schwannoma. Expansion in that area accounts for 10% of all intracranial tumors and causes a set of symptoms we call pontocerebellar angle syndrome.

 * cranial nerves: n. facialis, n. vestibulocochlearis
 * flocculus
 * lateral recess of the fourth cerebral ventricle

Symptoms

 * cerebellar syndrome
 * peripheral paresis of VII.
 * ipsilateral impairment of the corneal reflex
