Intracranial epidermoid cyst is a relatively rare disease accounting for 1.1% of all brain tumors and 3.0% of cerebello-pontine-angle (CPA) tumors. The neurological symptoms are similar to those caused by other CPA tumors, since the origin is anatomical. The clinical symptoms appear very slowly due to the embryologic origin, and few of the symptoms are typical. Consequently, accurate diagnosis is often difficult, and proper treatment is usually not possible.
We treated one patient with epidermoid cyst of the CPA, a 49-year-old woman with the chief complaint of glossopharyngeal neuralgia. She also had hearing loss and paresthesia of the trigeminal nerve.
CT & MRI were very useful in the diagnosis.
