title: Computed tomography of vertebral tuberculosis: patterns of bone destruction.
abstract: A retrospective analysis was performed of CT scans of 30 consecutive patients with a clinical suspicion or diagnosis of spinal tuberculosis. Four patterns of bone destruction were noted, namely, fragmentary, osteolytic, subperiosteal and well-defined lytic with sclerotic margins. The fragmentary type was most common (47%). Intervertebral disc destruction was always associated with contiguous vertebral body destruction. Associated paravertebral soft-tissue masses were seen in all patients. Epidural extension of disease was seen in 66% and showed a very good correlation with neurological signs on clinical evaluation. Bone fragments were detected in the epidural soft-tissue mass in 65% of patients with epidural extension of disease. CT appearances of bone destruction are highly suggestive of tuberculous osteomyelitis in about half the patients.
