Posted On 2020-05-10 04:58:36

In this brief letter we would like to refer to you some information about the value of CT imaging for corona virus disease 2019 (COVID-19) pneumonia in cases which have inconsistent COVID-19 nucleic acid test. A 34-year-old man had a 1-day history of fever (39.0 ℃) entered our hospital who resided in Wuhan, China (COVID-19 epicenter) but had traveled to Chengdu, China. The detection of Influenza A, B virus antigens was negative. Real-time fluorescence polymerase chain reaction of the patient’s nasopharyngeal specimen was positive for the COVID--19 nucleic acid test (NAT) (Jan. 22, 2020). Chest computed tomography (CT) (Figure 1, Jan. 22, 2020) displayed slightly high density and obscure patchy shadows in the apical segment of the right upper lobe, suggesting inflammation.
