目的探讨重症及危重症甲型H1N1流感病毒肺部感染的胸部影像表现.方法回顾性分析18例甲型H1N1流感并发肺炎患者的临床及影像资料,将其分为重症组(11例)及危重症组(7例),所有患者均经胸部X线检查,其中2例行CT检查.结果重症组11例,8例X线表现为双侧肺野中内带分布的、边缘模糊的小斑片和结节状阴影,3例X线表现为局灶性边缘模糊的片状阴影,其中1例胸部CT表现为右下肺大片实变影.危重症组7例,4例X线表现为双肺弥漫分布的磨玻璃密度阴影伴部分实变,其中1例出现胸颈部皮下气肿,1例胸部CT表现为双肺广泛分布的、沿支气管走行的斑片状磨玻璃密度影,双下肺结节状实变病灶和胸腔积液;其他3例表现为双侧肺野内大范围实变影.结论甲型H1N1流感肺炎的影像表现包括重症患者肺内的结节样和斑片状阴影,危重患者肺内弥漫的支气管周围分布的磨玻璃密度灶和多灶性实变.

Objective To evaluate the pulmonary imaging features in patients with severe or critical severe A H1N1 influenza. Methods Clinical and imaging findings of 18 cases with H1N1 pneumonia were retrospectively analyzed. These patients were divided into 2 groups including severe group (n=11) and critical group (n=7). Results Among the severe group, bilateral ill-defined nodules and patch shadows were found in 8 cases, local ill-defined patchy was shown in 3 cases, and consolidation of right inferior lung was demonstrated by CT scan in 1 case. Among the critical group, diffuse ground-glass attenuation with partial consolidation were found in bilateral lungs of 4 cases, subcutaneous emphysema was observed in 1 case. CT showed diffuse ground-glass attenuation and nodular like consolidation in bilateral inferior lungs in 1 case, and other 3 cases showed diffuse consolidation of bilateral lungs. Conclusions The radiologic findings of severe and critical severe pulmonary infections with H1N1 include ill-defined nodules and patch shadows of bilateral lung in sever patients, diffuse peribronchial ground-glass opacity and multifocal consolidation in critical severe patients. The radiologists should learn the features of H1N1 pneumonia on thoracic plain film and CT to make diagnosis in time.
