Abstract
Introduction: Involvement of spine in tuberculosis is most common skeletal manifestation of extra-pulmonary tuberculosis. It is a destructive process involving abscess, collapse of vertebra, end plate irregularities, cord abnormalities and intervertebral disc deformity. X-ray always remains initial imaging modality of choice followed by CT and MRI. Most commonly followed path of assessment includes X-ray and MRI, as bony abnormalities seen best on X-ray and soft tissue abnormalities on MRI. Present study was performed to assess imaging findings in spinal tuberculosis using X-ray and MRI.
Method and Materials: The study was conducted on 50 patients clinically suspected of spinal tuberculosis referred to radiology department for further workup. After taking an informed and written consent, X-ray was taken first, followed by MRI.
Results: Back pain is most common symptom of Spinal TB. Kyphosis, scoliosis, collapse of vertebra, cord edema, involvement of disc, abscess, canal stenosis, reduced bone density and thecal sac indentation were the findings seen in spinal tuberculosis patients. MRI was noted to be a better modality for the evaluation of the canal abnormalities and extent of abscess.
Conclusion: X-ray remains initial imaging modality due to easily available cheap modality and excellent demonstration of bony abnormalities. However, MRI remains best available modality due to its excellent soft tissue demonstration and marrow lesions.
Keywords: Tuberculosis, Pott’s spine, Extra-pulmonary, MRI, Spinal deformity.
