Cerebellopontine angle syndrome

The cerebellopontine angle is a niche in the rear area of ​​the brain near the temporal bone - on the cerebellar tonsils, under the bridge, next to the medulla oblongata - where to find in a confined space, the central portions of 10 of the 12 cranial nerves. Particularly emphasized structures that run through this area, the VII ( facial nerve ) and the eighth cranial nerve are ( vestibulocochlear nerve ), which converge in the cerebellopontine angle, the fifth cranial nerve ( trigeminal nerve ), the front and rear lower cerebellar artery ( cerebellar artery ), and the petrous sinuses ( petrosal sinus ) leading veins.

Pathological processes in the cerebellopontine angle often lead to complex symptoms, the functional deficits of the cranial nerves (usually the seventh and eighth ) and the cerebellum, as well as signs of increased intracranial pressure may include. Common causes are lesions; usually an acoustic neuroma, more rarely other tumors, local inflammation or altered vessels.
