传染性非典型肺炎首次阳性胸片分析

Study of positive findings on initial chest radiograph of patients with severe acute respiratory syndrome (SARS)

目的 :探讨传染性非典型肺炎初始发病时的胸部X线表现 ,提高该病的诊断符合率。方法 :回顾性分析 2 60例传染性非典型肺炎患者首次阳性胸片的X线表现。结果 :2 60例传染性非典型肺炎首次阳性胸片的胸部X线表现为斑片状影 176例 ( 67.7% ) ,大片状影 5 6例 ( 2 1.5 % ) ,间质改变 72例 ( 2 7.7% ) ,44例 ( 16.9% )斑片状影伴间质改变 ;单肺受累 117例 ( 4 5 .0 % ) ,双肺受累 14 3例 ( 5 5 .0 % ) ;163例 ( 62 .7% )片状影内可见支气管气像。结论 :斑片状影、大片状影、间质改变是传染性非典型肺炎首次阳性胸片的主要X线表现 ,胸片检查应作为传染性非典型肺炎常规检查方法。

Objective:To study the image appearances of the SARS on the initial chest radiographs of the patient,to improve the understanding about this disease.Methods:The positive findings on initial chest radiograph of patients with SARS were retrospectively analyzed.Results:The initial positive radiographic features of the 260 cases of SARS included:mottling of the lung field (n=176),patchy shadows (n=56),interstitial changes (n=72) and mottling with interstitial changes (n=44). There was unilateral involvement of the lung in 117 cases and bilateral in143.Air bronchogram within the patchy shadow was noted in 163 cases.Conclusion:Mottled,patchy and interstitial lesions are the main features on the initial chest radiograph of SARS.However,the final diagnosis should be made in combination with clinical and laboratory examination.
