严重急性呼吸综合征患者的胸部X线表现

Chest X-ray findings of severe acute respiratory syndrome patients

目的 :分析和总结严重急性呼吸综合征 (SARS)患者的胸部 X线影像特点 ,为 SARS的临床诊断和治疗积累资料并提供参考依据。方法 :回顾分析 2 0 0 3年 3月 5日至 3月 30日临床确诊的 2 8例 SARS患者床边胸部 X线表现 ,并对各病例急性期和恢复期的 X线表现进行了对比分析。结果 :在发病的急性期 ,13例呈单个片状影或小淡片状影及 3例呈同侧肺野 2个淡片状影表现者 ,病变均位于肺周边部 ;6例片状影在肺中心部位 (近肺门旁 ) ;6例双侧片状影 ;4例有两肺广泛片状影。在疾病的恢复期 ,急性期肺部病变范围小的 19例病灶完全吸收 ;病变较大的 9例 ,6例可见索条影 ,另 3例病变广泛者死亡。结论 :SARS患者的胸部 X线表现为多种实变阴影 ,其中单发小淡片影多位于肺周边部位且容易吸收 ;双肺及广泛实变影多位于中下肺野且吸收较慢。本研究结果初步提示

Objective:To study the chest X ray features in patients with severe acute respiratory syndrome (SARS), providing useful radiologic information for clinical diagnosis and treatment of SARS.Methods: From March 5, 2003 to March 30, 2003, 28 patients with SARS underwent chest radiograph in wards and the results were compared at acute stage and recovery stage.Results: At acute stage 13 cases had single opacity or small subtle opacity in peripheral lung;3 cases had 2 opacities in periphery unilaterally;6 cases had opacities in central lung;6 cases had opacities or consolidations bilaterally;4 cases had widespread consolidation. At recovery stage the lesions were all resolved in 19 slight cases;some strip and line shades showed in 6 severe cases and the other severe cases died. Conclusion: X ray of SARS are various consolidative opacities.Single subtle opacity is commonly located in peripheral distribution and easy to resolve; large and widespread consolidation was commonly located in middle and lower zone of bilateral lungs and not easy to resolve. The results demonstrate that extension of lesions were related to prognosis of patients with SARS.
