4. The chest radiograph shows overall interval worsening
The frontal chest radiograph shows patchy peribronchovascular thickening in the left lower lobe at the site of the previously noted somewhat rounded opacity at presentation chest radiography (Figure 1). Very faint abnormalities are now visible in the right lower lobe. Overall, the chest radiographic appearance has worsened compared to presentation, with new areas of involvement now visible (right lower lobe) and worsening of pre-existing abnormalities. No pleural effusion or lymphadenopathy is present.
The patient’s C-reactive protein level was trending downward compared with his initial hospitalization, as was his D-dimer level, the latter now 612 ng/mL (normal, ≤500 ng/mL). Repeat COVID-19 testing was positive. His ECG was normal and unchanged and initial troponin measurement was within the normal range.
