Progression of lung involvement on CT scans

A. Contrast-enhanced computed tomography (CECT) of the chest, showing bilateral multifocal areas of consolidation (arrows) with a rare air bronchogram in the right middle lobe (arrowhead) and no sign of necrosis or cavitation. Bilateral pleural effusion (★).

B. CECT of the chest, showing a partial regression of consolidation and additional air bronchograms in the upper segments of the lower lobes (arrows). Partial regression of bilateral pleural effusion (★).

C. Non-enhanced computed tomography (NECT) of the chest, showing small residual consolidations in the upper segments of the lower lobes (arrows). No pleural effusion.
