CT features and clinical characteristics of 8 cluster cases of imported COVID-19/ 八例境外输入聚集性发病的新型冠状病毒肺炎的CT表现及临床特征
To investigate the CT manifestations and clinical features of 8 cases of COVID-19 imported from abroad with clustering disease. Retrospective collection of clinical and CT imaging data of 8 patients with imported cluster disease confirmed on March 1 and 2, 2020 in Lishui City, Zhejiang Province. Eight patients were practitioners from the same restaurant in Italy, all returning from Milan, Italy. There were six males and two females, aged 30.0-40.0 (33.5 ± 3.3) years old. All patients underwent CT re examination 3-5 days after their first CT examination. All 8 patients had normal blood routine and no fever upon admission. Among them, 1 had dry cough and diarrhea, 1 had dry cough, and 6 had no obvious symptoms. The first CT scan showed multiple patchy, wedge-shaped ground glass or solid lesions in the pleura of both lungs in 3 cases, diffuse ground glass and solid lesions in 1 case, single lobar subpleural patchy ground glass lesions in 2 cases, and fibrous lesions in the middle and lower left lobes of the right lung in 1 case. The imaging appearance was normal in 1 case. After an interval of 3-5 days, CT scans showed significant absorption in 5 lesions, slight absorption in 1 case, and no change in 1 fibrous lesion. Non COVID-19 changes were considered. The COVID-19 patients with aggregation disease imported from overseas in this group did not have fever, and there was no decrease in white blood cell and lymphocyte counts. The CT imaging manifestations were diverse, but absorption was rapid, indicating that the clinical symptoms and CT manifestations of imported cases were more subtle and complex. It is necessary to be vigilant to avoid misdiagnosis.
