Introduction: Intramedullary spinal cord tumor (IMSCT) constitutes 8% to 10% of all primary spinal tumors with the majority comprised of gliomas (80% to 90%), of which 60% to 70% are ependymomas and 30% to 40% are astrocytomas. Astrocytomas are common in the thoracic region whereas ependymomas are common in cervical region. Ependymomas are the most common glial tumor in adults, whereas astrocytomas are the most common intramedullary tumor in children. Overall, 15% of all primary intramedullary spinal cord tumors are ependymal in origin and include one of three histopathologic subtypes: ependymoma, subependymoma and myxopapillary ependymoma. Aim of the Study: The aim of this study was to evaluate the role of MRI in diagnosis of intra medullary spinal tumors compared to histopathological findings. Methods: This was a cross sectional study and was conducted in the Department of Radiology and Imaging, Sylhet M.A.G. Osmani Medical College, Sylhet in collaboration with Department of Neurosurgery & Pathology of the same hospital, Sylhet, Bangladesh during the period from September, 2018 to August 2020. Result: In total 35 patients completed the study. In our study we found the Mean ± SD of age was 41.71±13.9 in years. Majority (57%) of our patients presented with intramedullary spinal cord tumor were male compared to female (43%).We found that among of our 35 patients 20 (57.14%) were ependymoma, 15 (42.86%) patients were astrocytoma diagnosed by MRI. Majority (40%) patients of ependymoma belong to 41-50 years and majority patients of astrocytoma (40%) belong to 10-20 years old. Both ependymoma and astrocytoma showed male predominance with 55% and 60% respectively. It was observed that majority (70% & 55%) patients of ependymoma had back & radicular pain respectively. Majority (80% & 60%) patients of astrocytoma had back & radicular pain respectively. Ependymoma was determined by calculating sensitivity 95.0%, specificity 100%, accuracy 97.14%, PPV 100% and NPV 93.75% ....
