In addition, PET scan revealed irregular band of parenchymal consolidation in the left lung superimposed with interstitial infiltrates extended over medial aspect of upper and lower lobes, encompassing hilar region, in addition to 2 enlarged lymph nodes measuring 32 mm and 31 mm diameters in upper anterior mediastinum that could represent either a chronic inflammatory process or neuroendocrine tumor of the left lung with secondary mediastinal lymph nodes (Fig. 3).
Multiple mediastinal lymph nodes, the biggest one subcarinal measuring 3 x 3 cm (white arrow), left and right hilar adenopathies on CT of the chest.

CT of chest and abdomen demonstrated multiple mediastinal lymph nodes, with the most prominent being sub-carinal measuring 3 x 3 cm with a necrotic center, left and right hilar adenopathies of 3.5 and 2.7 cm respectively (Fig. 4), bilateral pleural effusion, mainly on the left, left and right inferior lobe consolidations with air bronchogram and multiple liver lesions (Fig. 5).
