- Imaging findings can be variable, with most common patterns including peripheral rounded bilateral ground-glass opacities with possible progression to consolidations later in disease course; “crazy paving” can also be seen. Atypical findings that should prompt consideration of alternative diagnoses include single lobar infiltrate, cavitation, tree-in-bud pattern, and centrilobular nodules. Point-of-care ultrasound is also mentioned as a useful bedside imaging modality for evaluating possible thoracic complications of this disease, such as pneumothorax or pericardial and pleural effusions.

Findings on initial CT include bilateral multilobar ground-glass opacification (GGO) in a peripheral or posterior distribution, often in the lower lobes and less frequently in the right middle lobe. Less common findings include septal thickening, bronchiectasis, pleural thickening, and subpleural involvement. As disease progresses, pleural effusion, pericardial effusion, lymphadenopathy, cavitation, CT halo sign, and pneumothorax may be seen. Imaging during intermediate-phase disease may show an increase in number and size of GGOs, transformation of GGOs into multifocal consolidative opacities, and the development of crazy paving pattern. The greatest severity of CT findings is around day 10 after symptom onset.
