Abstract:
ObjectiveTo study the appearances and dynamic changes of chest high resolution computed tomography (HRCT) in clinically diagnosed critical influenza A (H1N1) pneumonia.MethodsOne hundred chest HRCT scanning examinations were performed in 36 cases of influenza A (H1N1) pneumonia who were diagnosed by the clinical manifestations in one month.The onset,progress and resolve of pulmonary manifestations were analyzed.Results Chest HRCT was performed in six patients,and small patchy opacity presented in three cases and ground-glass opacities presented in the other three cases within 3 days after onset when the disease was at the initial stage.Multiple larger opacities were visualized in all cases at the progressive stage (3 days later after onset),which included the pure ground-glass opacities (9 cases,25.0％ ),ground-glass opacities accompanied by consolidations (20 cases,55.6％),prominent consolidations (7 cases,19.4％),and accompanied pleural lesions (10,27.8％).The lesions strongly progressed within (8.0± 2.6) d and distinctly absorption in all cases (100.0％,36/36) within (16.0±4.8) d after onset of the disease.The pulmonary interstitial hyperplasia was found in 23 cases (63.9％).Dynamic change types of the lesions include absorption after progression,absorption and progression coexistence then absorption and gradually absorption,andabsorptionafterprogressionwas themajor type(41.7％).ConclusionHRCT could distinctly demonstrate the shape,range and dynamic changes of pulmonary lesions of critical influenza A (H1 N1) pneumonia.
