Key imaging findings of COVID-19 pneumonia on computed tomography (CT) of the chest
Diverse pattern of lung disease on CT with some key imaging features
Distribution	Bilateral, multilobar, subpleural, peripheral and basilar predominant
Pattern	Rounded morphology, ground-glass opacities (GGO) and multilobar consolidations
Uncommon findings	Mediastinal lymphadenopathy, pleural effusions, cavitations and pulmonary nodules
Initial findings	Typical pattern Normal in up to 25% patients
Progression	Lobar consolidations, pleural effusions, subpleural blebs and bullae may develop in severe illness
Organization	Early fibrosis and traction bronchiectasis may develop in severe ARDS in two to four weeks
