目的分析严重急性呼吸综合征(SARS)患者的胸部X线表现及其与临床经过的关系。方法分析了2003年4月17日至2003年5月20日经临床确诊的74例SARS患者的胸部X线表现并与其临床经过进行了对照。大部分病例是CR系列胸片资料。结果SARS患者的肺部影像表现有索条斑片影、磨玻璃样影、片状影、团块影及弥漫混合影。SARS患者肺部病变的分布以两肺中、下部为主(81%)。肺部病变的转归有4种模式:a)在发现病灶后3d～7d内基本吸收者占39%;b)病变进展扩大者占28%;c)2周以内在吸收过程中有复发者占22%;以及d)持续进展在2周以上者占11%。结论SARS患者肺部病变的发展有其自身的规律性,病变首次出现时间与病程密切相关,胸部X线表现是其诊断的重要依据。
Objective To analyze the chest X-ray findings in patients with severe acute respiratory syndrome (SARS) and its relationship with clinical course. Methods The chest X-ray findings of 74 clinically diagnosed SARS patients from April 17, 2003 to May 20, 2003 were analyzed and compared with the clinical data. Most cases are CR series chest radiographs. Results The pulmonary manifestations of SARS patients showed stripe patchy images, ground glass samples, patchy patches, patchy patches and diffuse mixed images. The distribution of lung lesions in patients with SARS mainly in the middle and lower lungs (81%). There are 4 modes of pulmonary pathological change: a) 39% of primary absorbents within 3d ~ 7d after the lesion is found; b) 28% of the lesion progresses; c) There are recurrences within 2 weeks during the absorption process Accounting for 22%; and d) 11% of those who continued to progress for more than two weeks. Conclusion The development of lung disease in SARS patients has its own regularity. The time when the disease first appears is closely related to the course of the disease. The chest X-ray manifestation is an important basis for its diagnosis.
