Aim: Intramedullary spinal cord tumors (IMSCT) are rare neoplasms of central nervous system but require proper evaluation and management to ensure a good outcome. This study was carried out to evaluate the functional outcome of IMSCT following surgery and to decipher the factors affecting optimal outcome of these cases. Materials and Methods: A prospective clinical study was carried out at a tertiary care center from 2003 to 2012. Forty three patients with intramedullary tumors diagnosed on magnetic resonance imaging were included. Their clinical details, neurological findings and demographic data were recorded. The patients were then subjected to surgery and adjuvant radiotherapy. The patients were followedup clinically and radiologically, and all parameters examined and recorded. Results: Sensory and motor impairment was present preoperatively in majority of patients (n = 39 and n = 38, 90.7% and 88.4%, respectively). Gross total excision was performed in 30 cases (69.76%). The most common histological diagnosis was ependymoma (n = 21, 48.8%). Postoperatively 32 patients (74.4%) were in McCormick functional Grade I or II improving from 13 cases (30.2%) in Grade I or II preoperatively. Fifteen of 17 patients in Medical Research Council (MRC) Grade III and 10 out of 12 patients in Grade MRC IV improved. No mortality was recorded during the entire period of follow-up (mean: 22, range: 3-96 months). Eight patients (18.6%) had recurrence till the last follow-up visit. Conclusions: Preoperative neurological grade was the most important predictor of functional outcome. Gross tumor excision was the best surgical modality to improve event free survival. High-grade tumors had higher rates of recurrence but no effect on functional outcome.
