Air-space opacities in the right middle and lower lobes, with lesser involvement of the right upper lobe, associated with a right pleural effusion, prominence of the right hilum, and paratracheal stripe widening. These findings raise concern for post-obstructive pneumonia with a possible mass and/or lymphadenopathy in the right hilar region. Alternatively, this may represent pneumonia with adenopathy. Clinical correlation and follow-up imaging are recommended for resolution. Consideration for further evaluation with contrast-enhanced CT of the chest is warranted.
