Purpose : To evaluate magnetic resonance (MR) imaging features of non-surgically treated tuberculous spondylitis and to evaluate the relationships between these features and clinical outcomes.
Materials and Methods : Data from ten patients (male:female=6:4, mean age=45 years) with clinically proven tuberculous spondylitis who were treated nonsurgically over three months were analyzed retrospectively from 2000 to 2007. MRI was performed at least three times for each patient, at baseline, every three or six months, and at the end of treatment. All images were analyzed by two radiologists.
Results : The mean follow-up period for the MR examination was 10.1 months (range, 4-17 months). Six patients had clinically complete resolution of tuberculous spondylitis with medication treatment only. Four patients were treated with surgical management alongside medication. All ten patients were divided into two groups by clinical outcome; six patients with complete treatment and four patients with incomplete treatment. In the complete treatment group, follow-up MR findings showed a loss of subligamentous spread of abscesses, decreased size of abscesses, no interval changes in vertebral body heights, and fatty changes in spinal lesions. MR findings in the incomplete treatment group showed bone marrow edema extension to adjacent vertebra, extension of the abscesses, and decreased height of the vertebral bodies.
Conclusion : During the nonsurgical management of tuberculous spondylitis, MR imaging may play a role in predicting patient response to antituberculous drug treatment.
