Aim: This prospective observational study aimed at finding out the efficient clinical and functional factors which affect the surgical outcome on the basis of location of the intradural extramedullary spinal cord tumors (IESCTs) and in follow up period of 1 year post surgery, treated at a single tertiary institution (Vivekananda Polyclinic and Institute of Medical Sciences, Lucknow). Material and Methods: We prospectively analyzed 44 consecutive cases of IESCTs diagnosed on radiology and operated at our center from 2014 to 2016. The demographic data, clinical presentation, tumor radiological parameters (axial and saggital location and tumor occupancy ratio), treatment modality, and follow up outcome of these patients are reviewed. We have excluded patients with Neurofibromatosis, recurrent tumors and intradural cauda equina and conus lesions. Result: A clinical series of 44 patients with IESCTs, underwent surgery (standard laminectomy) and excision of tumor have been followed for 1 year. The most commonly involved spinal level was dorsal (65.91%) followed by cervical (20.45%) and lumbar (18.18%) spine. The axial location of tumor was dorsal/posterior (6.82%), ventral/anterior (13.64%) while most common axial location of tumor was lateral (79.55%). We have found that the gait disability score and frankel score shows significant improvement within 1 week after surgery and after 1 year of follow up, 90.91 % patients have gait disability score of > 2 while frankel scale has shown, 81.82 % were ambulatory and only 18.18 % were non-ambulatory. Conclusion: Analysis of the MRI findings should be undertaken in a routine, standardized fashion to insure the accurate evaluation of the location of the tumor for planning the surgical interventions. As a surgeon we should be more cautious while operating on the purely ventrally located tumors through the posterior approach and we may prefer anterior approach in them. Similarly in saggital location, we should be cautious to operate the thoracic locating tumors to prevent the post-op complications.
