ABSTRACT

The aim of the present study was to observe the temporal changes in the chest based on findings from imaging in severe patients with novel coronavirus pneumonia. A total of 33 severe confirmed cases (20 male patients and 13 female patients) were enrolled in the present study between January 31, 2020 and March 10, 2020. Chest imaging findings and clinical data were collected and analyzed. The median age was 65 years (age range, 25­90 years). As of April 7, 2020, 24 patients were discharged, and 9 patients died. With regards to the clinical manifestations, 28 patients had fever, 17 patients had a cough and 15 patients had shortness of breath. Of these, 29 patients had underlying health conditions. Ground glass opacities, consolidation and interlobular septal thickening were the most common and typical chest computerized tomography (CT) scan abnormalities. A total of 6/33 (18.2%) patients had 1 affected lobe, 6/33 (18.2%) patients had 2 affected lobes, 5/33 (15.2%) patients had 3 affected lobes, 9/33 (27.3%) patients had 4 affected lobes and 7/33 (21.2%) patients had 5 affected lobes in the initial chest CT scan. The mean interval time between two consecutive CT examinations was 4.5 days (range, 3­9 days). Most severe patients exhibited some degree of aggravation based on the CT findings in the 3 weeks from illness onset. After 3 weeks from illness onset, these severe survivors demonstrated improvements in the chest CT findings, which included complete absorption or only a few remaining fibrous stripes. Chest CT manifestations of patients infected with novel coronavirus pneumonia were diverse and varied. Severe patients had imaging features of rapid progression and slow absorption. Monitoring of chest imaging findings is vital to detect any changes in a timely manner.
