目的 探讨儿童SARS的胸部X线特征 ,提高其诊断水平。方法 搜集 2 0 0 3年 1～ 4月住院确诊为SARS的患儿 3 5例 ,对其临床、X线资料进行回顾性总结分析。结果 儿童SARS的X线表现为大片实变型 2 7例 ( 77.1% ) ,间质浸润型 6例 ( 17.1% ) ,混合型 2例 ( 5.7% ) ,伴单、双侧肺气肿各 1例 ,全部病例未见肺脓肿和累及胸膜等表现。X线动态变化显示起病急 ,病变出现早 ,进展快 ,多在发病后 5～ 7d达到高峰。X线病变吸收较慢 ,常滞后于临床症状好转 ,超过 15d时基本吸收的占42 .9% ;同时 ,X线表现与临床体征不一致。结论 小儿SARS的X线表现有一定特点 ,诊断需认真分析其X线征象 ,密切结合临床和实验室检查
Objective To investigate the chest X-ray features of children with SARS and to improve their diagnostic level. Methods Totally 35 children diagnosed as SARS from January to April in 2003 were retrospectively analyzed in clinical and X-ray data. Results The X-ray manifestations of SARS in children were 27 cases (77.1%) of the large lumps, 6 cases (17.1%) of the interstitial infiltrates, 2 cases (5.7%) of the mixed type and 1 case of single and bilateral emphysema No pulmonary abscess and pleural involvement were found in all cases. X-ray dynamic changes showed acute onset, lesions appear early, rapid progress, and more in the onset of 5 ~ 7d peak. X-ray lesions absorbed slowly, often lagging behind clinical symptoms improved, more than 15d basic absorption accounted for 42.9%; the same time, X-ray findings and clinical signs are inconsistent. Conclusion X-ray findings of children with SARS have certain characteristics, the diagnosis should be carefully analyzed X-ray signs, in close combination with clinical and laboratory tests
