    Background Coronavirus disease MESHD 2019 (COVID-19) pneumonia HP pneumonia MESHD caused similar symptoms to other community-acquired pneumonia HP pneumonia MESHD (CAP). It is important to early quarantine suspected patients with COVID-19 pneumonia HP pneumonia MESHD from patients with other CAP to reduce cross infection MESHD. The purpose of the study is to review and compare initial thin-section computed tomography (CT) features in patients with coronavirus disease MESHD 2019 (COVID-19) pneumonia HP pneumonia MESHD and other community-acquired pneumonia HP pneumonia MESHD (CAP). Methods 24 cases of COVID-19 pneumonia HP pneumonia MESHD (14 males TRANS and 10 females TRANS; age TRANS range, 14-87 years; mean age TRANS, 48.0 years) and 28 cases of CAP caused by other pathogens (13 males TRANS and 15 females TRANS; age TRANS range, 24-85 years; mean age TRANS, 49.5 years) were included. Thin-section CT features of the lungs for all patients were retrospectively reviewed by two independent radiologists. Results There were no significant differences for the shape of main lesions, pure ground glass attenuation (GGA), mixed GGA with consolidation, air bronchogram, linear opacities, halo sign/reversed halo sign, cavitation and lymphadenopathy HP lymphadenopathy MESHD between the group of COVID-19 pneumonia HP pneumonia MESHD and the group of other CAP. However, the frequency of crazy-paving appearance, vessel dilatation HP, bilaterally involvement and peripherally distribution were significantly higher in patients with COVID-19 compared with other CAP ( p =0.031, p =0.000, p =0.029 and p =0.009, respectively). Conversely, the frequencies of pure consolidation, tree-in-bud sign and pleural effusion HP pleural effusion MESHD were significantly higher in patients with CAP than in patients with COVID-19 pneumonia HP pneumonia MESHD ( p =0.002, p =0.000 and p =0.048, respectively). Conclusion There are considerable overlaps in thin-section CT features between COVID-19 pneumonia HP pneumonia MESHD and other CAP. However, the presence of crazy paving pattern, vessel dilation, bilateral involvement and peripheral distribution contributes to the diagnosis of COVID-19 pneumonia HP pneumonia MESHD. While the presence of pure consolidation tree-in-bud sign, pleural effusion HP pleural effusion MESHD can be assisting in exclusive the diagnosis of COVID-19 pneumonia HP pneumonia MESHD.
