Figure 3. An axial chest CT images of a 77-year-old man who presented with progressive cough and shortness of breath for 2 days, placed side-by-side for comparison. The initial contrast-enhanced CT study (A) performed on day 6 of illness onset showed no evidence of ground-glass opacity or consolidation. A repeat plain CT study (B) obtained on day 14 of illness onset in view of worsening shortness of breath demonstrated new subpleural interstitial thickening at the posterior aspect of the right lower lobe (arrow). There were also small bilateral pleural effusions.
