CT findings in tuberculous spondylitis.

The computed tomographic (CT) features of ten documented cases of spinal tuberculosis were analyzed. All cases showed evidence of vertebral body destruction, with paravertebral soft tissue masses. Four cases revealed extension of involvement into the neural arches. Calcification within the paraspinal soft tissue was found in only two cases. Two of four cases who received intravenous contrast medium demonstrated evidence of rim enhancement around multilocuated fluid collections. Compared to conventional roentgenography, CT better delineated the extent of bony destruction, involvement of the spinal canal and existence of paraspinal soft tissue masses.
