Abstract
In December 2019, a highly infectious disease emerged in the city of Wuhan, China, causing severe respiratory distress syndrome which was later proven to have been caused by a novel coronavirus. (1) The WHO named the disease as COVID-19 and declared it as a pandemic on March 11, 2020. In the following weeks, the disease has swept rapidly across most of the countries of the world causing a global health emergency. As of April 14, 2020, the total number of cases has exceeded 1,800,000 with more than 110,000 deaths. (2) Chest CT has proven to have a significant role to help in diagnosis of this deadly disease also evaluating the disease progression and monitoring the response to therapy as it is cheaper, available, safe and time saving. (3) A wide variety of CT findings of COVID-19 have been reported in the different studies. It is including bilateral multifocal patchy areas of ground glass opacities, consolidation with air bronchogram , crazy pavement appearance that mostly present sub pleural and predominantly involving the lower lung lobes and posterior segments & other different signs that differ according to the stage of the disease, disease severity and associated co-morbidities . (4) This finding suggests that CT is a sensitive modality with which to detect COVID-19 pneumonia, even in asymptomatic individuals, and could be considered as a screening tool when a patient has significant travel history or has close contact with an infected individual.
