摘要
目的 探讨急性传染性非典型肺炎(SARS)的X线表现及变化规律。方法 回顾性分析临床诊断SARS的61例患者,对发病后的一系列胸片和CT影像进行统计分析。结果 患者以发热为最早起病症状,88.5％患者在起病1周内肺部出现肺局灶性斑片状模糊影,并迅速扩大。2周内病变过高峰,有57.4％患者两肺大部分肺野受累,病情重。83.6％患者在5周内肺部阴影逐渐消散。在恢复期16例CT扫描中,有13例显示肺部遗留纤维化病灶。有6例患者合并感染,病期延长,4例死亡。结论 SARS早期出现肺部炎性改变.发展迅速,大部分两肺受累,重症比例高,易致肺纤维化。
Objective To evaluate the appearance and dynamic change of chest roentgenography and CT in severe acute respiratory syndrome (SARS) . Methods Serial roentgenography and CT of 61 confirmed SARS patients were analyzed. Results The onset symptom was fever in all patients. In the early phase of SARS, the main abnormal appearance was single or bilateral localized patchy clouding opacity on roentgenography, which progressed rapidly. The area of opacity reached the peak at about 2 weeks, with 57.4% involving most area of the lung. The area involved was correlated with the severity of the clinical symptoms. The opacity disappeared gradually in 5 weeks in 83.6% of the patients. Complicated lungs infection was found in 6 cases with prolonged duration of the illness. Among the 61 cases, 4 cases died. CT scan was performed in 16 SARS patients in the recovery phase. Lungs fibrosis was found in 13 out of the 16 cases. Conclusion In SARS patients, lungs infiltration was found in early phase, which developed rapidly and involved most area of the lungs in the advanced phase in majority of the cases. Lungs fibrosis was found in some patients in the recovery phase.
