摘要
目的 探讨严重急性呼吸综合征 (SARS)的影像学特点。方法 对经专家组临床诊断SARS患者 15例 ,进行连续隔日床旁X线胸片为主进行分析。结果 ( 1)病变部位 :双侧或多叶占 66.67% ,下肺多见。 ( 2 )病变形态及追踪 ,在起病之初类圆形片状影占 78.2 6% ,其余尚可见磨玻璃影 ,粗网状影。病灶无肺叶、肺段形态。随病情的变化 ,病灶形态可以变化 ,可以进展为成人呼吸窘迫综合征 (ARDS)“白肺”。治疗后 5例占 3 3 .3 3 %有遗留表现 ,粗网影 4例 ,出现细网状间质纤维化 1例。 ( 3 )病灶中心密度高 ,边缘较淡 ,形似棉絮。 ( 4 )病灶吸收时间 6～ 2 9d ,平均 15 .2 7d。 ( 5 ) 4例占 2 6.67%在 2d内病灶范围增大 5 0 %。( 6) 2例“白肺”出现胸腔积液。结论 SARS影像学表现与常见病毒性及细菌性肺炎具有较特征性的表现。
Objective To investigate the radiological characteristics of severe acute respiratory syndrome (SARS).Methods 15 patients who were clinically proved as SARS (8 men and 7 women;mean age,32.4 yr) involved in the investigation.The chest radiograph findings of patients were analyzed.Results (1) The position of lesion:most of the lesions located in the lower part of lungs,and the lesions in both lobes of lung or numerous lung lobes maked up 66.67%.(2) The shape of lesion and trace:at early period the lesions of roundish shadow in shape accounted for 78.26%,the other lesions showed the ground glass opacification or thick reticular shadow.The lesions didn't show lung segments or lung lobes in shape.With the progression of the patients'conditions,the shape of lesions changed,and some lesions developed to 'white lung'.After treated,5 cases (33.33%) still left over some lesions,4 cases showed the reticular shadow,only one was found thin reticular pulmonary interstitial fibrosis.(3) Lesions were like cotton fiber in shape,with high density in center and lower density around.(4) Lesions were absorbed from 6 to 29 days (mean time,15.27 days).(5) The area of lesions of 4 cases (26.7%) increased by 1.5 times within 2 days.(6) Two cases of 'white lung' showed hydrothorax.Conclusion The radiological findings of SARS are characteristic,as compared with those of viral pneumonia and bacterial pneumonia.
