Background: Lower lung eld tuberculosis is dened as tuberculosis with involvement of lower lung elds without simultaneous involvement of upper lobe. Lower lung eld tuberculosis when encountered for the rst time often suggest a diagnosis other than tuberculosis such as pneumonia, bronchogenic carcinoma, bronchiectasis or lung abscess. Hence this study was designed to nd out the clinico-radiological prole of lower lung eld tuberculosis cases.

The relative risk of having the lower lung eld tuberculosis in diabetes patients, HIV, renal disease patients was high. Conclusion: Lower lung eld tuberculosis is not an uncommon entity.
