- Choroid plexus tumours: a surgically treated seriesPublication . Barbosa, MD; Rebelo, O; Barbosa, P; Lacerda, A; Fernandes, RChoroid plexus tumours-carcinomas and papillomas are 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.
- Cystic intraventricular schwannoma: case report and review of the literaturePublication . Barbosa, MD; Rebelo, O; Barbosa, P; Gonçalves, J; Fernandes, RIntraventricular schwannoma is an exceedingly rare tumour with only 6 cases described in the literature. One case of a cystic intraventricular schwannoma operated on at our Institution is analyzed and the other cases reported in the literature are reviewed. Complete removal was achieved and no recurrence was noted after a follow-up period of 10 years. Intraventricular schwannomas are rare tumours that are amenable to complete surgical removal, having a good prognosis without the need of adjuvant therapy.
