Cerebellopontine Angle Syndrome

Cerebellopontine Angle Syndrome

Lesions of the cerebellopontine angle produce a constellation of ipsilateral signs:

• Depressed corneal reflex, impaired corneal sensation (early sign);
• Lower motor neurone facial (VII) weakness;
• Sensorineural hearing loss (VIII);
• Hemiataxia.

The most common causes of this syndrome are acoustic neuroma (schwannoma) or meningioma; occasional causes include dermoids, epidermoids (cholesteatoma), and chordoma.
