The cerebellopontine angle CPA arachnoid cysts are rare and often asymptomatic. The onset of symptoms and signs is usually due to the compression of the brain, cranial nerves and obstruction of CSF circulation. The major clinical symptoms for CPA arachnoid cysts were reported as headache, ataxia and 8 th cranial nerve palsy. We report a patient with a CPA arachnoid cyst.

Objective: The optimal surgical management of arachnoid cysts remains controversial. The cerebellopontine angle CPA is a rare location for arachnoid cysts, and only 28 cases of arachnoid cysts occurring in the CPA have been reported in the literature. We discuss the diagnosis, radiographic imaging, and surgical management of CPA arachnoid cysts. Methods: Five patients three male and two female patients with a mean age of 5. Magnetic resonance imaging allows for the accurate diagnosis of these arachnoid cysts, which can present with only discrete symptoms, such as headache or ataxia. All five arachnoid cysts compressed the cerebellum or brain stem. One patient had associated hydrocephalus. Three patients presented with refractory headaches associated with nausea and vomiting. The remaining two patients presented with cerebellar signs. No patient had an initial cranial neuropathy.

Mirror movements are involuntary movements, which occur in a muscle group or limb on one side of the body in response to an intentionally performed movement in corresponding contralateral muscle group or limb.

The cerebellopontine angle CPA is a rare location for arachnoid cysts, and fewer than 35 cases of arachnoid cysts occurring in the CPA have been reported in the literature. We discuss the diagnosis, radiographic imaging, and management of CPA arachnoid cysts. Arachnoid cysts often present with only subtle signs or symptoms, such as headache or ataxia. Our case involves a middle-aged, female patient, who presented with unilateral tinnitus, unsteadiness, and headaches associated with nausea and vomiting. On clinical examination there were no cerebellar signs or cranial neuropathy; she did, however, suffer from a unilateral mild to severe hearing loss. Recent advances in MRI magnetic resonance imaging scan techniques have led to more frequent diagnosis of CPA arachnoid cysts and with a higher degree of certainty. These lesions have a characteristic location in the posterior-inferior aspect of the CPA below the facial and vestibulocochlear nerves.

Medulloblastoma MB is the most common malignant pediatric brain tumor arising in the cerebellum or the 4 th ventricle. In this study, we sought to describe the clinical characteristics, molecular features and outcomes of CPA MB. We retrospectively reviewed a total of patients who had a histopathological diagnosis of MB at the Beijing Neurosurgical Institute between and
