Abstract

Objects: The aim of this study is to describe the characteristics of spinal tumors on magnetic resonance imaging (MRI). Materials and Methods: A descriptive cross-sectional study on 49 patients of spinal tumors was documented with MRI and surgical treatment at Viet Duc University Hospital from July, 2019 to September, 2020. Results: The study showed the average age of patients was 47,2±16,8, out of which the proportion of the age between 51 and 60 was highest, at 26,5%. Extramedullary and intramedullary tumors comprised 87,8% and 12,8% of all cases, respectively. The common tumors were neurinoma (38,8%) and meningioma (20,4%). On MRI, the most common location of tumors is thoracic spine with 40,8% of cases. The average tumor size was 35,9±33,5mm. There were 95,9% of tumors having well-defined boundaries and 87,8% of tumors extended into spinal cord and/or spinal nerve roots at the same level. Tumors with isointense signal on T1W comprised 51%, with hyperintensity on T2-weighted MRI was 40,8%. There were 93,9% of tumors enhanced on postgadolinium. Conclusion, MRI plays an important role in identifying the anatomic location, the size, the degree of neural compression and suggesting histopathology of spinal tumors.
