© 2020 Elsevier LtdDespite their rare occurrence, intramedullary spinal cord tumors can cause considerable morbidity and mortality without treatment. Timing of surgery, extent of resection and selection of favorable treatment option are important considerations for a good surgical outcome. In this clinical study, we report our patient series and convey our treatment strategy. We retrospectively reviewed 91 patients with primary intramedullary spinal cord tumors who underwent microsurgical resection at our institution between 2008 and 2018. Data were collected consisting of age, sex, location and histology of tumor, extent of resection, presenting symptoms and neurological outcomes. Modified McCormick Scale was used to assess neurological status of patients. 47 female and 44 male patients were followed-up for a mean period of 35.7 months. The most frequent pathological diagnosis was ependymoma in 56 patients, followed by astrocytoma in 21 and hemangioblastoma in 5 patients. The rest of the tumors consisted of 3 cavernomas, 3 mature cystic teratomas, 2 PNET, one epidermoid tumor. Gross total resection was achieved in 67 patients, while subtotal resection and biopsy was performed in 15 and 9 respectively. The most commonly involved localization was cervical (n = 39), followed by thoracic region (n = 24). Despite immediate postoperative worsening of neurological status, a great number of patients improved at the last follow-up. Gross total resection remains the primary goal of treatment while adjuvant radiation and/or chemotherapy may be alternative options for high grade tumors. Preoperative neurological status was the most important and the strongest predictor of functional outcome.
