1A, 1B and 1C (From left to right clockwise): Admission CXR shows low lung volumes with left lower lobe peripheral parenchymal opacities. CT shows right upper lobe and bilateral lower lobe nodular areas of peribronchovascular and peripheral airspace opacification.. Fig. 1D, E and 1F (From left to right clockwise): Readmission imaging with features of worsening basilar predominant interstitial thickening and right lower lobe atelectasis and central and peripheral areas of ground glass opacities.

CT chest showed diffuse peripheral predominant bibasilar and right upper lobe ground glass opacities (Fig. 1). CTA of the chest ruled out pulmonary embolism and showed worsening nodular ground glass opacities in the upper lobes (Fig. 1).

2A & 2B (clockwise from left to right): Admission CXR with bilateral atelectasis. Admission CT chest notable for mild airway inflammation and bilateral trace pleural effusions.. Fig. 2C: Discharge CXR is unchanged.. Fig. 2D and E and (From left to right): Readmission CXR with diffuse patchy airspace disease throughout the left lung and moderate patchy airspace disease in the right lung markedly progressed. Readmission CT chest with extensive multifocal GGO.

3A & 3B (left to right clockwise): Admission CXR with nodular right upper lobe opacity. Admission CT chest showing multifocal peripheral distribution of GGO.. Fig. 3C: Discharge CXR showing improved right upper lobe opacity with linear atelectasis at the bases.. Fig. 3D and E and (left to right): Readmission CXR with patchy bilateral opacities. Readmission CT chest demonstrates diffuse GGO with crazy paving.. Fig. 3F, G & 3H: CT angiogram shows features of bilateral lower lobe thrombi Readmission CT chest demonstrates diffuse GGO with crazy paving.

CT chest demonstrated multifocal ground glass opacities most pronounced in the right upper lobe (Fig. 3). CT chest showed progression of diffuse ground glass opacities with crazy-paving (Fig. 3).

4A, 4B, 4C, 4D (From left to right clockwise): Admission CXR with bibasilar opacities. CT Urogram with images of the lung bases demonstrate peripheral subpleural ground glass nodules as highlighted Fig. 4D: CXR from day of discharge unchanged.. Fig. 4D and E: Readmission CXR with mild increase in left upper lobe and bibasilar opacities. CT chest on readmission reflects bilateral GGO.
