| Abstract|| |
COVID-19 pneumonia is a serious health issue in the current pandemic caused by SARS-CoV-2. PCR testing is limited due to a number of factors and imaging has role in decision-making for many of these patients. We present computed tomography chest images of patients hospitalized with suspicion of COVID-19 pneumonia and point out the common and uncommon features on imaging to assist management of these patients.
Keywords: Coronavirus disease 2019, computed tomography chest, pneumonia, severe acute respiratory syndrome coronavirus-2

The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is the seventh coronavirus causing human disease and is responsible for the current pandemic of coronavirus disease 2019 (COVID-19). While the diagnosis of COVID-19 is made by polymerase chain reaction (PCR) viral identification, this has been hampered by the test's availability, turnaround time, as well as low sensitivity. Chest CT has been used for early diagnosis of COVID-19 pneumonia: it has correlated well with PCR and in some cases better for a diagnostic yield in in conjunction with comprehensive assessment.,, The spectrum of imaging findings may represent a temporal association of disease onset with timing of CT imaging as well as severity of disease (i.e., cytokine storm).,, The common findings include peripheral, multifocal, sometimes diffuse subpleural ground-glass opacities (GGO) with or without consolidation, GGO with interlobular septal thickening (“crazy-paving”), and in the later phase, organizing pneumonia pattern and patchy atelectasis [Figure 1]., These findings, in the right clinical scenario, should highly raise concern for COVID-19. On the other hand, uncommon findings include lobar consolidation, tree-in-bud nodules, cavitation, pleural effusion, and large lymphadenopathy and should raise concern for coexistent or alternate etiologies [Figure 2].,

Chest computed tomography has a value in detection as well as potentially in severity assessment of hospitalized patients with COVID-19 pneumonia. This will become clearer as understanding of this novel disease further improves and robust prospective trials become available.
