摘　　要：目的 分析甲型H1N1流感胸部X线及CT表现,提高对甲型H1N1流感胸部影像学表现的认识.方法 收集2009-10-2010-01符合甲型H1N1流感诊断标准的51例患者临床及影像学资料,对其临床及影像学资料进行了初步回顾性分析和总结.本组51例确诊甲流患者,年龄14～66岁.结果 临床表现为流感样症状,大部分伴有发热、流涕、鼻塞、咽痛、咳嗽、头痛、肌痛、乏力等,5例未出现发热.病变累及单侧肺2例（ 3.92%,2/51 ）,累及两肺49例（96.08%,49/51）.肺部病变表现为多形态改变占46例,肺部同时出现淡薄片状、云絮状及磨玻璃样影.肺部病变表现为单形态改变5例,以双肺纹理增多、纹理间散在小片状影.47例影像学表现变化以进展-逐渐吸收模式多见,11例在出院后出现条索状影,部分复查后条索影吸收好转.结论 甲型H1N1流感肺部病变多出现于双侧下肺,可表现为单样性或多样性病灶,病变的发展变化过程较为迅速,影像学检查在病变的诊断和治疗及疗效评价中具有重要价值.Objective To analyse the chest X--ray and CT features of H1N1 A influenza,so that to improve the imaging understanding of this diseases. Methods The clinical and imaging data in 51 cases with A H1N1 influenza confirmed clinically from Octo- ber 2009 to January 2010 were collected and these data were retrospectively analysed. The age of the patients ranged from 14~66 years old. Results The clinical＇symptoms included fever,runny nose,sore throat,cough,headache,muscle pain,weakness,while 5 cases without fever. Unilateral lung lsions in 2 cases （ 3.92%, 2/51 ） and bilateral lungs lesions in 49 cases （ 96.08%, 49/51 ） were showed. Various changes of lung including thin clouds and ground glass shadow presented in 46 cases. 5 cases appeared as lung marks increased and multiple patches. The lesions were worse and then absorbed gradually in 47 cases. After discharge, 11 cases remained cord--like shadows or absorbed partly. Conclusion The pulmonary lesions in A H1N1 influenza appear as simple or various features on imaging and are changed rapidly, imaging examination has an important value in the diagnosis, treatment and evaluation of this disease.
