Summary

Choroid plexus tumours carcinomas and papillomasare rare, especially in adults, and they pose some problems in their diagnosis and management.

We have reviewed a series of nine cases from our institution surgically treated during the last 18 years. Their clinical charts, neuroradiological examinations, surgical technique, neuropathology and follow-up were analysed.

In only one case total removal proved to be impossible, but even in cases of total removal recurrence appeared in two cases (one carcinoma and one papilloma). Morbility is especially associated with posterior fossa tumours.

These rare tumours are managed surgically. They are usually associated with hydrocephalus, and it is difficult to forecast whether or not permanent CSF drainage will be required. A long-term follow-up is needed in patients with this type of tumour.

Resumen

Los tumores de los plexos coroideos –carcinomas y papilomas- son raros especialmente en el adulto y plantean diversos problemas en su diagnóstico y tratamiento.

Hemos revisado una serié de nueve casos tratados quirúrgicamente en nuestro servicio durante los últimos 18 años, analizando los datos de la historia clínica, los exámenes neurorradiológicos, la técnica quirúrgica y el estudio neuropatológico.

Solo en un caso se estimó imposible la resección tumoral y en otros dos ocurrió recurrencia (un carcinoma y un papiloma) a pesar de haberse llevado a cabo una resección aparentemente total. Los tumores localizados en la fosa posterior se asociaron a una mayor morbilidad.

Los tumores de los plexos coroideos deben ser tratados quirúrgicamente. Se asocian generalmente a hidrocefalia y es difícil de predecir cuando los pacientes van a necesitar derivación permanente de líquido cefalorraquídeo. Los pacientes con este tipo de tumor deben ser seguidos por períodos largos de tiempo.
