目的探讨严重急性呼吸综合征的胸部CT表现以及在诊断和治疗中的价值。方法回顾性分析经临床、流行病学、放射学、实验室检查确诊的18例严重急性呼吸综合征患者的CT资料,其中男8例、女10例,平均34岁。结果18例中有9例表现有片絮状阴影,其中7例见两下肺外带大片棉絮状密度增高阴影,2例为一侧上肺外带小片状密度增高阴影合并另侧肺大片状阴影;18例中有7例见磨玻璃样影,其中双侧全肺1例,两侧下肺3例,单侧下肺2例,单侧上肺1例;1例表现单侧斑片状合并小网状结节影;1例表现为一侧下肺片絮状合并另一侧上肺磨玻璃样影。结论严重急性呼吸综合征的胸部CT表现以不按肺叶或肺段分布的片絮状渗出灶或磨玻璃样淡薄阴影为主。多叶同时受累和双下肺外带多见。
Objective To investigate the chest CT findings of severe acute respiratory syndrome (SARS) and its value in diagnosis and treatment. Methods The CT data of 18 patients with severe acute respiratory syndrome confirmed by clinical, epidemiological, radiological and laboratory tests were retrospectively analyzed. There were 8 males and 10 females, with an average of 34 years. Results Of the 18 cases, 9 showed flaky shadows, of which 7 were seen on both flanks of the lungs with large patches of cotton density increasing shadows, 2 on one side of the pulmonary banding flaps with increased density shadows combined with the other side of the lungs Flake shadow; 7 cases of 18 cases of ground glass-like shadow, including bilateral all-lung in 1 case, bilateral lower lung in 3 cases, unilateral lower lung in 2 cases, unilateral upper lung in 1 case; 1 case showed unilateral Patchy merged with small reticular nodules; 1 case showed the side of the lung piece flocculent combined with the other side of the lung-ground glass-like shadow. Conclusion The chest CT findings of severe acute respiratory syndrome are mainly based on the flecked exudative foci or ground glass-like faint shadow, which are not distributed in the lobe or lung segments. Multi-leaf involvement and double lower lung takeaway more common.
