摘要
目的 探讨严重急性呼吸综合征 (severeacuterespiratorysyndrome ,SARS )的X线特征。方法 对 2 9例已确诊为SARS患者的临床资料和X线表现进行总结分析。结果 本地区有SARS爆发流行。本组病例均以发热为首发症状。 15例 (51 7% )病人有咳嗽 ,多为干咳。 10例 (3 4 5% )患者入院前使用抗生素治疗无明显效果。血白细胞计数正常 18例 (62 1% )、降低 11例 (3 7 9% ) ;血小板计数轻度降低 7例 (2 4 1% ) ;肝功能异常 16例 (55 2 % ) ,主要表现为血清酶学的改变。肺部体征轻微 ,与X线胸部阴影显著的表现不相符。其胸部X线表现为 :肺纹理增多伴网状阴影 7例 (2 4 1% ) ,磨玻璃状阴影 3例 (10 4% ) ,斑片状阴影 12例 (41 4% ) ,片状阴影 7例 (2 4 1% )。X线改变出现晚、吸收慢。结论 SARS患者的X线表现各异。结合流行病学史、临床表现、实验室检查和影像学检查可明确诊断。
Objective To study the X-ray features of severe acute respiratory syndrome (SARS ). Methods The clinical data and X-ray appearances of 29 cases with SARS were analyzed retrospectively. Results Epidemic outbreak of SARS has occurred at this area. 29 cases of SARS in this group began with a fever. 15 cases (51.7%) experienced mild respiratory symptoms. In 10 patients (34.5%) the antibacterial medication showed inefficacy before hospitalization. Leucocyte counting was normal in 18 cases (62.1%) and decreased in 11 cases (37.9%). Platelet counting slightly decreased in 7 cases (24.1%). Hepatic function test was abnormal in 16 patients (55.2%), mostly with a decrease of serum enzymology. Obvious abnormalities were seen on the chest films, which were in sharp contrast with the mild clinical respiratory signs. Chest X-ray findings were as follows: Exaggerated and indistinct lung markings with reticular shadow in 7 cases (24.1%), ground-glass opacity in 3 cases (10.4%), small patchy and multi-patchy imaging in 12 cases (41.4%), and large patchy shadow in 7 cases (24.1%). X-ray abnormality was presented later and absorbed slower. Conclusion SARS carries a variety of X-ray appearances. The combined use of epidemiologic history, clinical situation, laboratory tests, and imaging examinations can make a definite diagnosis.
