The cerebellopontine angle syndrome
From WikiLectures
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.
