Abstract 【Objective】 To explore the application value of MRI in the differential diagnosis of brucellar spondylitis and spinal tuberculosis. 【Methods】The MRI data of 40 cases with brucellar spondylitis and 50 cases with spinal tuberculosis from January 2012 to October 2016 were retrospectively analyzed. 【Results】There were significant differences between the brucellar spondylitis group and the spinal tuberculosis group in the sites of destroyed vertebral bodies [front side, back side and both sides (25.00%, 60.00%, 15.00%) vs (68.00%, 16.00%, 16.00%)], abscess in paravertebral soft tissues (7.50% vs 74.00%), intervertebral disc destruction [limited, diffuse (45.00%, 17.50%) vs (18.00%, 40.00%)], intervertebral space stenosis (27.50% vs 50.00%), intervertebral disc signal abnormalities (80.00% vs 30.00%) and intervertebral space disappearance (0.00% vs 20.00%) (P<0.05). The pathogenic sites, number of vertebral involvement and the incidence of kyphosis showed no significant differences (P>0.05). 【Conclusion】 The MRI findings such as pathogenic sites and number of vertebral involvement in brucellar spondylitis and spinal tuberculosis are similar, but the differences in the sites of vertebral destruction and intervertebral space stenosis are significant, which can be used as important MRI signs for the differential diagnosis of the two diseases.
