title: [Choroid plexus papilloma of the cerebellopontine angle. Presentation of a case and review of the literature].
abstract: Choroid plexus papillomas of the cerebellopontine angle are quite rare. Up to date, 19 cases surgically removed have been reported (table I). We describe the case of a 25 year old man with a choroid plexus papilloma (C.P.P.) who presented only two syncopes in the interval of 4 months. A computed tomographic scan revealed a calcified right extra-axial tumor occupying the cerebellopontine angle and a moderate degree of obstructive hydrocephalus. A vertebral angiogram showed that the tumor was avascular. A right suboccipital craniectomy was performed and the mass was excised in totality. The patient was discharged from hospital 2 weeks after surgery. 10 months later, neurological findings were normal. Histological examination exhibited a typical papilloma of the choroid plexus. The differential diagnosis of tumors in the C.P.P. angle is discussed. Total surgical excision in the treatment of choice. Radiation therapy could be used when the resection is incomplete.
