目的 报道严重急性呼吸综合征 (SARS)的胸部X线表现。方法 分析 10 5例SARS患者的胸部X线表现及特征。所有患者均为在 2 0 0 3年 1月 30日至 3月 31日期间进行诊治、并符合中华人民共和国卫生部制定的传染性非典型肺炎临床诊断试行标准 ,且在住院治疗期间有完整胸部X线片资料的患者。病变根据早期表现和进展情况分为 4型。 (1)局限型 :由肺内单一局部病灶到病变发展或广泛分布。 (2 )多发型 :早期即见肺内多发片状或 (和 )结节状病灶。 (3)间质 实质型 :以肺部间质性炎症为早期主要表现 ,其后出现明显的肺实质渗出性病变。 (4)间质型 :以肺间质异常为主要表现。结果 SARS患者的胸部X线表现形式多样 ,75例表现为肺内渗出性实变病灶 ,其中局限型 5 7例 ,多发型 18例。 2 5例呈间质性炎症征象 ,随后出现明显肺内实变。 5例主要表现为肺间质性炎症。首次见肺内病变至病变完全吸收的时间为 7～ 46d ,平均为 19d。结论 SARS的X线表现以肺实质渗出性病变和间质性炎症为主 ,病变早期发展迅速 ,肺内实变于首诊后 7～ 10d达高峰 ,其后大部分患者可完全吸收。绝大多数患者预后良好 ,目前尚未见后遗症。
Objective To report the chest X-ray findings of severe acute respiratory syndrome (SARS). Methods The chest X-ray findings and characteristics of 105 SARS patients were analyzed. All patients were diagnosed and treated between January 30, 2003 and March 31, 2003, and were in line with the pilot diagnostic criteria of SARS developed by the Ministry of Health of the People’s Republic of China. They also had complete chest during hospitalization X-ray data of patients. According to the early signs of disease and progress divided into 4 types. (1) localized type: the development of a single lesion from the lung to the lesion or widely distributed. (2) multi-hair type: early that multiple lungs or flakes (and) nodular lesions. (3) interstitial substance: interstitial lung inflammation as the early main performance, followed by obvious pulmonary parenchymal exudative lesions. (4) Interstitial type: the main manifestation of interstitial lung abnormalities. Results The manifestations of chest X-ray in patients with SARS were diverse. 75 patients showed intrapleural exudative solid lesions, of which 57 were localized and 18 were multiple. 25 cases were interstitial inflammation signs, followed by significant consolidation of the lungs. 5 cases mainly as interstitial inflammation. The first time to see the lung lesions to lesions completely absorbed time is 7 ~ 46d, an average of 19d. Conclusions X-ray manifestations of SARS are mainly pulmonary exudative and interstitial inflammatory diseases. The early development of the disease is rapid. The intra-lung consolidation reaches a peak at 7-10 days after the first diagnosis, and most of the patients can completely absorb. The vast majority of patients with good prognosis, has not yet seen the sequelae.
