The pandemic COVID-19 caused by the 2019 novel coronavirus called severe acute respiratory syndrome coronavirus-2 displays a very heterogeneous clinical behaviour. The majority of patients (>85%) are asymptomatic or have mild symptoms, while few others show a very aggressive and life-threatening disease. Imaging spectrum of COVID-19 is very heterogenous as well: from normal picture in patients with mild symptoms such as fever and dry cough (figures 1 and 2) to pneumonia with multiple patchy, peripheral, bilateral areas of ground-glass opacity (GGO) and consolidation as in more severe illness (figures 3–8). A quick evolution of the disease is also seen. Involvement of both lungs seems to be the main imaging feature (75–100% of cases)1 2 usually with GGOs (77–91%)1 3 and consolidations (55–69%)1 3 in peripheral regions. Pleural effusions may occur in…
