Introduction and Methods: We retrospectively analyzed 111 patients with spinal tumors operated over a period of 9 years to observe the relative frequency of different lesions, their clinical profile, functional outcome and prognostic factors. 30/111 (27%) were extradural, 40/111 (36.1%) were intradural extramedullary (IDEM) and 41/111 (36.9%) were intramedullary spinal cord tumors (IMSCTs). Mean age at surgery was 30.81 years (range 1-73 years). The average preoperative duration of symptoms was 16.17 months (15 days to 15 years). Major diagnoses were ependymomas and astrocytomas in IMSCT group, schwanommas and neurofibromas in IDEM group, and metastasis, lymphoma in extradural group. The common clinical features were motor weakness in 78/111 (70.27%), sensory loss in 55/111 (49.54%), pain 46/111 (41.44%), and sphincter involvement in 47/111 (42.43%) cases. Results: Totally, 88/111 (79.27%) patients had improvement in their functional status, 17/111 (15.31%) remained same, and 6/111 (5.4%) were worse at time of their last follow-up. The mean follow-up was 15.64 months (1.5 m−10 years). Totally, 59 out of 79 patients, who were dependent initially, were ambulatory with or without the aid. Most common complication was persistent pain in 10/111 (9%) patients and nonimprovement of bladder/bowel symptoms in 7/111 (6.3%). One patient died 3 months after surgery. Conclusions: (1) Congenital malformative tumors like epidermoids/dermoids (unrelated to spina bifida) occur more frequently, whereas the incidence of spinal meningioma is less in developing countries than western populations. (2) The incidence of intramedullary tumors approaches to that of IDEM tumors. Intramedullary tumors present at a younger age in developing countries. (3) Rare histological variants like primitive neuroectodermal tumors should also be considered for histological differential diagnosis of spinal tumors. (4) Preoperative neurologic status is the most important factor related to outcome in spinal tumors.
