Diversas lesiones tumorales pueden estar en rela-ción con el sistema ventricular ocasionando con fre-cuencia hidrocefalia obstructiva. El objetivo de este trabajo es evaluar la utilidad de la neuroendoscopia en el manejo de las lesiones tumorales ventriculares tanto en su vertiente diagnostica corno terapèutica.
Presentamos una serie de 19 pacientes con lesiones tumorales ventriculares, biopsiadas endoscópicamente entre los añnos 1992–95. Ambos tipos de endoscopio, rígido y flexible, fueron utilizados. En 8 casos se realizó una ventriculostomía adicional para resolver un cuadro de hidrocefalia. La efectividad diagnóstica alcanzada fue del 73,6% (9 gliomas, 2 craneofaringiomas, 1 linfoma, 1 germinoma y 1 pineoblastoma). Se discute la morbilidad de esta técnica y se comparan sus resultados con los de procedimientos estereotáxicos.
Different brain tumours may appear within or beside the ventricular system. Most of them produce obstructive hydrocephalus. The purpose of our study is to evaluate the usefulness of neuroendoscopic procedures for diagnostic and therapeutic management of ventricular tumors.
We studied a series of 19 patients with ventricular tumors that underwent endoscopic biopsy beetween 1992–95. Both types of endoscope, rigid and flexible- steerable, were employed. In order to resolve hydrocephalus 8 patients underwent an endoscopic ventriculostomy. Diagnosis was obtained in 73,6% of the cases (9 gliomas, 2 craniopharyngiomas, 1 Iymphoma, 1 germinoma and 1 pineoblastoma). We discuss the morbidity and compare the resuIts with those reached by stereotactic procedures.
