3. Frontal chest radiography shows focal consolidation
The frontal chest radiograph shows a focal poorly defined opacity projected over the left hilum located in the posterior lung, probably in the superior segment of the left lower lobe (Figure 2).
Figure 2. Frontal (A) and lateral (B) chest radiography obtained around the time the patient was diagnosed with COVID-19 shows focal poorly defined opacity projected over the left hilum (A, arrow) located in the posterior lung (B, arrows). No pleural abnormality, pulmonary nodules, or evidence of mediastinal or peribronchial lymph node enlargement is present.
These findings are not typical of coronavirus infection; the typical manifestations of COVID-19 at chest radiography include multifocal, bilateral peripheral poorly defined pulmonary opacities without pleural effusion or visible lymph node enlargement.
