Frequency and distribution of chest radiographic abnormalities suggestive of inactive tuberculosis (n = 206).

*113 chest radiographs were interpreted as normal. 11 radiographs had lesions suggestive of possible active TB, one of whom (cavitary lesion with surrounding consolidation) was positive for acid fast bacilli. Radiological lesions in remaining ten (air space consolidation 7, hilar adeopathy 3) resolved either spontaneously or after antibiotics. A total of 244 abnormalities were reported in the remaining 206 radiographs.‡Of the 10 individuals with a non-calcified nodule, 4 had a single nodule, and 6 had between 2 and 5 nodules. The size of the largest nodule was between 1.5 to 3 mm in 2, and between 3 and 10 mm in 8 of them.†The four individuals with non-tubercular pulmonary abnormality had radiological features of chronic obstructive airway disease in addition to calcified nodules suggestive of inactive tuberculosis.§The non-pulmonary abnormality was cardiomegaly and pulmonary hypertension in addition to calcified nodules suggestive of inactive tuberculosis.
