The cerebellopontine angle is the space between cerebellum and pons. The angle is the site of subarachnoid cistern that contains cerebrospinal fluid, arachnoid tissue, cranial nerves and associated vessels. In cerebellopontine angle syndrome deficit occurs due to closeness of angle leading to unilateral hearing loss, speech impediment, disequilibrium, tremors or loss of motor control. It is also the site of growth of acoustic neuroma. The cause of the condition is unknown. A neuroma is associated to neurofibromatosis type 2. Diagnosis is done by MRI, CT scans or electronystagmography. Disease management options include: surgery or radiation therapy.
