    Abstract

    In this retrospective case series, chest CT scans of 21 symptomatic patients from China infected with the 2019 Novel Coronavirus (2019-nCoV) were reviewed with emphasis on identifying and characterizing the most common findings. Typical CT findings included bilateral pulmonary parenchymal ground-glass and consolidative pulmonary opacities, sometimes with a rounded morphology and a peripheral lung distribution. Notably, lung cavitation, discrete pulmonary nodules, pleural effusions, and lymphadenopathy were absent. Follow-up imaging in a subset of patients during the study time window often demonstrated mild or moderate progression of disease as manifested by increasing extent and density of lung opacities.

    • Key Points of Clinical and CT Imaging Features of 2019 Novel Coronavirus (2019-nCoV) Imported Pneumonia Based on 21 Cases Analysis 19 Pages Posted: 28 Feb 2020 Zhifeng Xu Government of the People's Republic of China - Department of Radiology Wenxiu Wu Government of the People's Republic of China - Department of Radiology Abstract Background and Objective: WHO Director-General declared that the 2019-nCoV outbreak constitutes a Public Health Emergency of International Concern,and the outbreak is still on-going.Chest CT had been a key component of the diagnostic workup for patients with suspected infection. In this retrospective study, we attempt to summarize and analyze the chest CT features of 2019-nCov infections, and to identify the typical features to improved the diagnostic accuracy of new coronavirus pneumonia (NCP).

    • A 33-year-old woman presented to the hospital with a 5-day history of fever and cough of unknown cause. She indicated that she worked in Wuhan, China (the center of novel coronavirus outbreak) but had traveled to Lanzhou, China, 6 days before presentation to the hospital. At admission, her body temperature was elevated to 39.0°C (102.2°F) and coarse breath sounds of both lungs were heard at auscultation. Laboratory studies showed leucopenia (white blood cell count: 2.91 × 109/L). The white blood cell differential count showed 70.0% neutrophils and 0.1% eosinophils. There were elevated blood levels for C-reactive protein (16.16 mg/L; normal range, 0–10 mg/L), erythrocyte sedimentation rate (29 mm/h; normal range, <20 mm/h), and D-dimer (580 ng/mL; normal range, 500 ng/mL). Unenhanced chest CT showed multiple peripheral ground-glass opacities in both lungs (Figure, A) that did not spare the subpleural regions. Real-time fluorescence polymerase chain reaction of the patient’s sputum was positive for the 2019 novel coronavirus (2019-nCoV) nucleic acid. On the basis of epidemiologic characteristics, clinical manifestations, chest images, and laboratory findings, the diagnosis of 2019-nCoV pneumonia was made. After receiving 3 days of treatment, combined with interferon inhalation, the patient was clinically worse with progressive pulmonary opacities found at repeat chest CT (Figure, B). Unenhanced CT images in a 33-year-old woman. A, Image shows multiple ground-glass opacities in bilateral lungs. Ground-glass opacities are seen in the posterior segment of right upper lobe and apical posterior segment of left superior lobe. B, Image obtained 3 days after follow-up shows progressive ground-glass opacities in the posterior segment of right upper lobe and apical posterior segment of left superior lobe. The bilateralism of the peripheral lung opacities, without subpleural sparing, are common CT findings of the 2019 novel coronavirus pneumonia.
