摘要
目的探讨人感染H7N9禽流感的胸部影像表现。方法搜集7例经临床确诊为人感染H7N9禽流感患者的临床和影像学资料,分析其胸部影像表现。发病初期主要临床表现有发热(7例)和咳嗽(4例)。结果人感染H7N9禽流感发病初期(〈3d)5例表现为局限于肺段或肺叶分布的磨玻璃影或实变灶,其中3例不跨越叶间裂,4例内有明显的空气支气管征;进展期(3~6d)病变迅速发展至两肺,呈多发或弥漫分布(7例),此期死亡4例;余3例患者中2例吸收期(7~15d)病灶部分吸收后显示为条索状、网格状及蜂窝状影。结论人感染H7N9禽流感主要影像表现为肺段或肺叶性渗出性病变,并迅速进展为两肺弥漫分布,影像学检查有助于掌握病情变化。
Objective To investigate the chest imaging features in H7N9 subtype human avian influenza. Methods The clinical and imaging data of 7 patients with HTN9 subtype avian influenza were collected and the chest imaging manifestations were analyzed. Results The main clinical symptoms of H7N9 patients were fever ( n = 7 ) and cough ( n = 4 ). The ground-glass opacities or consolidations in pulmonary segmental or lobar distribution were showed (n =5 ) at the initial stage (within 3 days ). Air bronchogram could be found in 4 cases. The bilateral lungs were rapidly involved with multiple or diffuse distribution (n = 7 ) at the progressive stage (3--6 days ), and 4 patients were died at this stage. The linear, reticular and honeycomb shadows were seen with partial absorption of lesions ( n= 2). Conclusion The main imaging features of H7N9 subtype human avian influenza are the segmental or lobar consolidations on the initial stage and rapid involvement of bilateral lungs with disease progression.
