ABSTRACT ABSTRACT ABSTRACT ABSTRACT ABSTRACT
Objective: The objective of this study is to determine the frequency of various types of Intradural extramedullary
tumors.
Methodology: This was an observational study conducted in the Neurosurgery Unit, Lady Reading Hospital Peshawar
from 1st
October 2010 to 1st
October 2011. Patients of all ages with either sex were included. Patients of spinal tumors
having diabetes mellitus, hypertension and ischemic heart disease,and previously operated were excluded from the
study. All the patients were operated under GA in a prone position and Laminectomy, Duratomy and Gross total
resection of the tumor was done. We did follow up for 6 months in the form of 4 weekly visits. Data was stratified
regarding age, sex and locality. Results were analyzed and presented in the form of tables and pie charts using
SPSS software version 11 for analysis.
Results: We studied 52 patients with spinal tumors out of which 30 (57.69%) patients had Intradural extramedullary
spinal tumors. Of the total 30 patients with intardural extramedullary spinal tumors, 17 were male and 13
females.Common clinical feature was neck pain and backache in 20 (66.6%) patients, leg weakness in 23 (76.6%)
cases, and poor sphincters were observed in 9 (30%) cases.MRI spine was the main diagnostic tool and was done
in 30 (100%) cases. Dorsal spine was involved in 16(53.3% ) cases while cervical spine was involved in 9(30%) and
lumber spine in 5(16.6%) patients . Neurofibroma was the commonest 14(46.66%) Intradural extramedullary tumor,
while others were meningioma 11(33.37%), F.T ependymoma 2(6.6%), dermoid 1(3.33%) , lipmoa 1(3.33%)hydatid
cyst 1(3.33%).
Conclusion: Neurofibroma and meningioma were the most common intradural extramedullary tumors.
