Purpose: To evaluate CT findings of tuberculous pneumonia mainly presenting as parenchymal consolidation. Materials & Methods: CT scans of twenty patients with tuberculous pneumonia were retrospectively reviewed.Analyses included the location ,extent, and homogeneity of consolidation, presence of volume loss of involved lungand air-bronchogram, associated lesions suggesting previous tuberculous infection and evidence of bronchogenicspread. Results: The location of consolidation revealed relatively even distribution without any specificpredilection site. The areas of consolidation were irregular in margin(95%), inhomogeneous in attenuation(75%)including focal areas of low attenuation and multiple cavities within it. Volume loss(70%) of the involved lobewas associated. There were lesions suggesting previous tuberculous infection(95%) in the surrounding area andevidences of bronchogenic spread(100%) such as poorly-defined nodules and lobular consolidations in the remotesite from main consolidation. Conclusion: In tuberculous pneumonia, the areas of consolidation are irregular inmargin and inhomogeneous in attenuation on CT scan. The evidences of bronchogenic spread and lesions suggestingprevious tuberculous infection are almost always associated in the surrounding or remote site from mainconsolidation.
