PURPOSE: To describe the radiologic findings in patients with spinal tuberculosis (TB). MATERIAL AND METHODS: Out of a total of 503 patients with TB, 63 (13%) had involvement of the spine. RESULTS: In 40 patients, the spine was the only location; 20 patients had concomitant chest TB. Conventional radiographs gave a good overview, CT visualized the disko-vertebral lesions and the paravertebral abscesses, while MR imaging was useful to determine the spread of disease to the soft tissues and the spinal canal. The typical findings were destroyed vertebrae with associated paraspinal soft-tissue mass, with or without abscess formation, sometimes also involving the epidural space together with adjoining disk lesion and focal gibbus formation. Involvement of a single vertebra was a relatively common finding. Large psoas abscesses could occur without any signs of bone involvement. The TB process could sometimes be indistinguishable from malignant processes, and in 3 patients, with multiple lesions in the spine, it mimicked metastatic disease. CONCLUSION: It is stressed that TB should always be considered in the differential diagnosis when radiologic findings suggest spinal infections or primary or secondary spinal tumors.
