Choroid Plexus Tumor Located in Extra-Ventricular Area : A Case of Pigmented Choroid Plexus Carcinoma: A Report of a Case

ABSTRACT

A Case of pigmented choroid plexus carcinoma is reported. The patient was a 35-year-old woman who had headache of 3-month duration, followed by ataxia for 1month before admission. Brain CT revealed a well enhanced mass at the left cerebello-pontine angle area as well as hydrocephalus. Subtotal removal of the tumor was performed via suboccipital craniectomy under the impression of meningioma because there was a mass only in the extraventricular area. The tumor was diagnosed by light microscopic examination. Pigmented choroid plexus carcinoma, which has been reported as low grade malignancy, is very rare and located always in the ventricles. In the case the tumor was subtotally removed and ventriculo-peritoneal shunt surgery and radiation therapy underwent later. The patient has been followed-up without recurrence for 1 year postoperatively.
