NSRG-24. OUTCOME OF SINGLE-TRAJECTORY ENDOSCOPIC THIRD VENTRICULOSTOMY AND BIOPSY IN THE MANAGEMENT ALGORITHM OF PINEAL REGION TUMORS: A CASE SERIES AND REVIEW OF THE LITERATURE

摘要

Tumors within the pineal region represent 1.5 to 8.5% of the pediatric brain tumors and 1.2% of all brain tumors. A management algorithm has been proposed in several publications. The algorithm includes endoscopic third ventriculostomy (ETV) and biopsy in cases presenting with hydrocephalus. In this series we are presenting the efficacy of a single-trajectory approach for both ETV and biopsy.METHODSThirteen cases were admitted to Alexandria main university hospital from 2013 to 2016 presenting with pineal region tumors and hydrocephalus. Mean age of at diagnosis 12 years (1 - 24 years). All cases had ETV and biopsy using rigid ventriculoscope through a single-trajectory from a burr-hole planned on preoperative imaging. Follow-up period was 7 - 59 months.
