Abstract

  Background: Intradural extramedullary spinal cord tumours prevelance approximately two thirds of all intraspinal neoplasm. Current study designed to analyze the clinical history, radiological aspects and resectability to identify the incidence of variou tumors in intradural extramedullary compartment and their management to understand the surgical outcome. Methods: 35 patients with intradural extramedullary tumors were thoroughly evaluated to know the symptoms and signs with particular stress on motor and sensory deficits and evaluated with MRI. Intradural extramedullary tumors were surgically managed by posterior or posterolateral approach and they were followed up regularly to measure the outcome. Based on Nurick grading scheme, patient’s ambulatory status was classified. Results: Most of the tumors belong to intradural extramedullary spinal tumors (60%) in total spine tumors and Nerve sheath tumours incidence is 37%. Mean age of meningioma patients was 38 years and nerve sheath tumour patients was is 40 years. Male predominance (70%) in nerve sheath tumour. Thoracic region is the mostly affected area. 85% of cases were excised their tumor. Mean follow up period was 11 months, no recurrence of tumor noted clinically. Immediate improvement is seen in (60%) and gradual improvement is seen in (30%). Conclusion: In the current study, intradural extramedullary tumors detected by MRI are mostly benign and good clinical results can be obtained by treated surgi­cally. Total surgical excision potentially minimizes neurologic morbidity and improved outcome.
