Imaging appearances of Corona Virus Disease 2019 (COVID-19) pneumonia overlap considerably with other infectious and non-infectious processes. Amongst many different features reported in the literature, a few patterns on Computed Tomography (CT) chest examinations have a higher specificity and predict a greater likelihood of having COVID-19 pneumonia. We aim to provide a pictorial representation of each of the commonly reported signs of COVID-19 pneumonia on CT chest examinations to aid the radiology residents, radiologists as well as the clinicians in identifying the most common imaging manifestations of this disease.

Educational Goals / Teaching Points
To review the typical imaging findings of COVID-19 pneumonia on CT chest examinations based on the Radiological Society of North America (RSNA) consensus statement. To describe and illustrate the common radiological signs associated with COVID-19 pneumonia described in the literature.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
The most commonly described imaging signs of COVID-19 pneumonia on CT include following the focal or diffuse ground-glass opacities in a peripheral distribution; crazy-paving; peripheral air-space consolidations; sub-pleural lines or fibrotic bands; spider-web sign; air-bronchograms; vessel enlargement in the vicinity of airspace abnormalities and reverse-halo sign.

Familiarity with the common CT features of COVID-19 pneumonia is necessary in order to distinguish from other acute pulmonary processes and to guide clinical management.
