Background: Since the first case of a coronavirus disease MESHD 2019 (COVID-19) infection MESHD pneumonia MESHD pneumonia HP was detected in Wuhan, China, a series of confirmed cases TRANS of the COVID-19 were found in Southwest China. The aim of this study was to describe the imaging manifestations of hospitalized patients with confirmed COVID-19 infection MESHD in southwest China.
Methods: In this retrospective study, data were collected from 131 patients with confirmed coronavirus disease MESHD 2019 (COVID-19) from 3 Chinese hospitals. Their common clinical manifestations, as well as characteristics and evolvement features of chest CT images, were analyzed.
Results: A total of 100 (76%) patients had a history of close contact TRANS with people living in Wuhan , Hubei. The clinical manifestations of COVID-19 included cough MESHD cough HP, fever MESHD fever HP. Most of the lesions identified in chest CT images were multiple lesions of bilateral lungs, lesions were more localized in the peripheral lung, 109 (83%) patients had more than two lobes involved, 20 (15%) patients presented with patchy ground glass opacities, patchy ground glass opacities and consolidation of lesions co-existing in 61 (47%) cases. Complications such as pleural thickening HP, hydrothorax MESHD, pericardial effusion MESHD pericardial effusion HP, and enlarged mediastinal lymph nodes were detected but only in rare cases. For the follow-up chest CT examinations (91 cases), We found 66 (73%) cases changed very quickly, with an average of 3.5 days, 25 cases (27%) presented absorbed lesions, progression was observed in 41 cases (46%), 25 (27%) cases showed no significant changes.
Conclusion: Chest CT plays an important role in diagnosing COVID-19. The imaging pattern of multifocal peripheral ground glass or mixed consolidation is highly suspicious of COVID-19, that can quickly change over a short period of time.
