摘　　要：目的　探讨传染性非典型肺炎的肺部 X线特征及其与临床表现的关系。方法　分析 39例传染性非典型肺炎的肺部 X线及临床表现。结果　肺部 X线改变出现在发热 4 .4± 2 .2日之后 ;35例病灶分布在下叶背段及后基底段为主。 2 0例 (5 1.3% )在治疗中肺部病灶进展 ,呈大片状阴影 ;19例在出现肺部病灶增加时 ,体温下降 ,全身中毒症状明显好转。在 2 2例重症中 ,治疗前外周血淋巴细胞 <1.2× 10 9/ L有 18例。结论　传染性非典型肺炎是一组起病急、肺部病灶出现快和以双肺下叶背段及后基底段病变为主的肺炎。对于血淋巴细胞计数减少的患者 。Objective To find out the relationship between the characteristics of chest X-rays and the clinical manifestations for severe acute respiratory syndrome (SARS).Methods Thirty-nine cases with SARS were analyzed using X-rays and observed with clinical examinations. Results The changes in the lung X-rays appeared 4.4 days ( STD:2.2) after the patients showed the signs of fever.The focus in the pulmonary fields was distributed in low lobes in 35 cases. There were 18 cases (81.8%) with <1.2*109/L in lymphocyte among the total of 22 severe SARS cases. The focus in the pulmonary fields for 20 patients with severe SARS was quickly developed after 9.9 days (2.6).Conclusion SARS is one type of pneumonia with acute and fast progressive development with the focus most in lower lobes of pulmonary fields. The patients with lymphocyte <1.2×10 9/L may be easily developed into severe SARS within 2 weeks.
