CASE 122 57-year-old man with long-standing cardiac dysrhythmias on anti-arrhythmic pharmacotherapy who now complains of dyspnea on exertion, dry cough, and weakness Unenhanced chest CT (lung window) (Figs. 122.1A, 122.1C, 122.1E) demonstrates patchy ground glass opacities in both lungs and focal mass-like regions of consolidation in the lingula, left lower lobe, and lateral segment right middle lobe. Corresponding mediastinal windows (Figs. 122.1B, 122.1D) reveal the focal areas of consolidation are higher in attenuation (89 HU and 87 HU, respectively) than the soft tissues (38 HU). Unenhanced CT through the liver (Figs. 122.1F) shows it is also higher in attenuation than normal.
