Craniopharyngioma of the posterior fossa.

A case of craniopharyngioma originating in the very unusual location of the posterior fossa is presented. The patient, a 23-year-old man, was operated on at another hospital when he was 3 years old for craniopharyngioma in the suprasellar area. There was no complaint for several years after this initial operation. Three months before he was admitted to our hospital, he had complaints of headache, vomiting, nausea, and ataxia. A computed tomographic scan revealed a mass with a cyst and calcifications in the posterior fossa. The tumor was removed totally.
