严重急性呼吸道综合征(SARS)的HRCT表现

HRCT Findings in Severe Acute Respiratory Syndrome(SARS)

目的 :分析严重急性呼吸道综合征 (SARS)的HRCT表现,提高对本病的认识水平。材料和方法 :回顾分析31例SARS患者的首次HRCT资料。结果 :SARS的HRCT表现为伴有或不伴有小叶间隔和(或)小叶内间质增厚的毛玻璃样改变 (61.3 % )、气腔实变 (16.1 % ) ,或同时兼有毛玻璃样改变和气腔实变 (22.6 % )。病灶可单侧(41.9 % )或双侧 (58.1 % )分布 ,多数 (71.0 % )累及2个或2个以上肺野 ,病灶主要分布于肺外侧带 (58.1 % )或同时分布于肺外侧带和中内侧带 (38.7 % )。结论 :SARS的HRCT表现缺乏特异性 ,但HRCT表现有助于本病鉴别诊断。

Purpose:To analyze the HRCT findings and enhance the knowledge of severe acute respiratory synˉdrome(SARS).Materials and Methods:Initial HRCT scans in31patients with SARS were studied retrospectively.Results:HRCT findings in SARS included ground-glass opacity(61.3%)with or without interlobular septal and/or intralobular interstitial thickening,air space consolidation(16.1%)and mixed ground-glass opacity and consolidation(22.6%).The involvement was unilateral(41.9%)or bilateral(58.1%).A majority(71.0%)of patients involved2or more than2lung fields.The lesions were predominantly located in outer zone(58.1%)or mixed outer and inner zones(38.7%).Concluˉsion:HRCT findings in SARS were nonspecific.However,these findings may be helpful in differential diagnosis.
