title: [Choroid plexus tumours: epidemiologic comparative study of 24 cases].
abstract: Tumours derived from choroid plexus are rare central nervous system neoplasms affecting mainly children. This study presents a series of 38 patients with neuroectodermal tumours. Twenty four of them had the histological and/or immunohistochemical diagnosis of choroid plexus carcinoma (CPC). Sixteen of these patients were male. The left lateral ventricle was affected in most cases. Main clinical features were: hydrocephalus, intracranial hypertension and convulsion. All the patients were treated by surgery. There were 2 deaths due to surgical complications. Nine patients had recurrence, dying in a intermediate time of 12.3 months and 7 patients remain alive. The other cases did not present available data. CPC is very prevalent in Curitiba when compared to other choroid plexus tumours and it might be related to some pathogenic agent.
