Chest X-ray showed an inhomogeneous opacity in the left lower zone with raised left diaphragm (Figure 1), and CECT (contrast-enhanced computer tomogram) chest showed a hypodense lesion with irregular margins in the anterior segment of the left lower lobe adjacent to the descending aorta and associated subcarinal lymphadenopathy (Figures 2 and 3).
