| Objective To explore chest high-resolution CT (HRCT) imaging features and outcome of Corona Virus Disease 2019 (COVID-19), and to improve the imaging awareness of COVID-19.Methods The clinical and chest CT data of 80 cases, diagnosed with COVID-19 in Anqing Municipal Hospital Affiliated to Anhui Medical University from January 22, 2020 to February 25, 2020,were analyzed retrospectively.Results Among the 80 cases of COVID-19 there were more males (60%) than females, and the mainsymptoms were cough, fever and fatigue. There were 7 mild cases, 72 ordinary cases, and 1 critical case. Except that the chest HRCTfindings of 7 mild cases and 2 ordinary cases showed negative, the chest HRCT findings of the other 71 COVID-19 were characteristic. Thirteen cases (18.3%) were involved unilaterally, and 58 cases (81.7%) were bilaterally. Twenty-eight cases (48%) involved the lowerlobe of both lungs, 33 cases (46%) the medial subpleural zone, and 38 cases (54%) around the bronchial vascular bundle. Chest HRCTof fifty-two cases (73%) showed patches and nodules, 14 cases (20%) integrated large flakes, and 5 cases (7%) strips. Pure ground glassopacity (pGGO) or mixed ground glass opacity (mGGO) were found in 34 cases (47.8%), coexistence of GGO and consolidation in 24cases (33.8%), fibre stripe in 4 cases (5.6%), GGO mixed with consolidation and fibre stripes 9 cases (12.7%). There were 6 cases(8.5%) with typical paving stone sign , 64 cases (90%) with inflatable bronchus sign, 8 cases (11.2%) with pleural thickening, 3 cases(4.2%) with reverse halosign, and 6 cases (8.5%) bronchiectasia. Mediastinal and hilar lymph nodes were enlarged but no pleural orpericardial effusion was found. Among 80 discharged patients, lesions in the lung were absorbed in 54 cases, and obvious residual fiberstrips were found in 16 cases.Conclusions Early HRCT manifestations of COVID-19 were multiple, subpleural, patchy/nodular, pG‐GO or mGGO, with interstitial changes or not. In the progressive stage, COVID-19 presented central consolidation or increased fibrosisand decreased GGO. In the outcome stage, most of the lesions were completely absorbed, but fibrous focus remained in some cases. |
