C, white blood count was 9.4 x 109/L (reference level < 8.3), procalcitonin was 0.33 microg/L (reference level < 0.5), and N-terminal pro-brain natriuretic peptide was 7220 (reference level < 194). Computed tomography of the chest showed ground-glass opacities and consolidation most pronounced in the right lung but no pulmonary emboli (Figure 1).
