ICD-9	191.6 - Malignant Neoplasms of brain: Cerebellum NOS: Cerebellopontine angle

The cerebellopontine angle is the anatomic space between the cerebellum and the pons. This is a common site for the growth of acoustic neuromas. When the surronding anatomy proximity of cerebellopontine angle to specific cranial nerves is taken into account, a distinct neurologic syndrome of deficits occurs.^[1]

[edit] Signs and Symptoms

Lesions in the area of cerebellopontine angle cause signs and symptoms secondary to compression of nearby cranial nerves, including cranial nerve V, cranial nerve VII, and cranial nerve VIII.

Involvement of CNV from a cerebellopontine mass lesion often results in loss of the ipsilateral corneal reflex.
