[|Human|] My mother (50 yr) is suffering from back pain . MRI detected a slight change in D12 vertebra but no injury happened. She was advised a Novartis Nasal Spray and been taking it from past 45 days but their is no relief. Now some doctor want to do a Bio scan and one doctor have advised some blood test like TC/DC, ESR , TB PCR. Please advise the necessary test required to detect BONE TB and what all disease can occur as per symptoms defined above.
[|AI|]  Hi, Dorsal spine involvement is a common association of spinal tuberculosis or Potts spine. If there is associated ongoing fever, reduced appetite, loss of weight or previous tuberculosis/tuberculosis exposure, tuberculosis is most likely. Blood counts, erythrocyte sedimentation rate, DNA PCR and contour test are the initial set of investigations that would be needed. Other causes could be degenerative osteoporosis / tumor / secondary metastatic lesions. Bone scans will be able to differentiate and rule them out.  Hope this information is helpful. Regards
