Computed tomographic evaluation of TB spine in Ibadan.
BACKGROUND
Tuberculosis still remains a major problem in the developing countries. The involvement of the spine is also of increasing importance, because of the resurgence of TB in association with AIDS. This paper is designed to evaluate the applicability of CT in the diagnosis and definition of tuberculosis of the spine in Ibadan.


METHODS
A restrospective study of the Computed Tomographic examination of 22 cases of spinal tuberculosis (Pott's disease) over a four-year period at the Radiology Department of the University College Hospital, Ibadan.


RESULTS
There was a male prevalence in the study. The mean age of respondents was 41.2 years. Neurological symptoms and back pain were the most common presentations. The thoracic spine was mostly involved while the cervical spine was least involved. Most lesions 77.3 % were demonstrated in two contiguous vertebral bodies. The vertebral bodies were destroyed in all the patients while the posterior elements were involved in 59%. The other CT findings were paravertebral soft tissue shadow in 40.9%, narrowed irregular disc spaces in 27.3% and fusion of vertebral bodies in 13.6%. The frequent bony destruction was osteolytic in nature, and was present in 64% of patients.


CONCLUSIONS
CT is an adequate modality for thorough imaging and diagnosis of Pott's disease especially in patients with non specific or ambiguous presentations. It offers a unique opportunity of demonstrating clearly the various component of the spine, it also defines the pattern and extent of the destructive process.
