49例肺隔离症临床特点分析

Clinical features of pulmonary sequestration: An analysis of 49 cases

目的分析肺隔离症患者的临床特点。方法对本院2008年7月-2016年5月确诊的49例肺隔离症患者的临床特点进行回顾性分析。结果 49例肺隔离症患者中,男25例、女24例,肺隔离症临床主要表现为发热、咳嗽、咳痰等肺部感染症状,但无特异性,自发病至确诊最短时间5 d,最长时间10余年,平均确诊时间14.23个月,中位确诊时间4个月。行增强肺CT检查者47例,影像学表现可见实性或囊性占位性病变,诊断依据为增强后可见病灶部位由体循环动脉供血。结论对于反复长期咳嗽、咳痰并伴发热,经抗感染治疗好转后易反复发作的患者,普通CT表现为实性或囊性占位,应高度怀疑肺隔离症可能,尽早行增强CT/MRI以明确诊断。

Objective To investigate the clinical features of pulmonary sequestration（PS）. Methods Clinical data and imaging characteristics of 49 patients diagnosed with pulmonary sequestration who admitted to Chinese PLA General Hospital from July 2008 to May 2016 were retrospectively analyzed. Results Of the 49 cases, there were 25 males and 24 females with no specificity in clinical symptom. The duration from onset to diagnosis was 5 d to more than 10 years with average time of 14.23 months and median time of 4 months. Forty-seven patients underwent contrast enhanced CT, and solid or cystic lesion could be found. Lung lesion receiving blood supply from an anomalous systemic artery was the diagnostic criterion. Conclusion Pulomonary sequestration should be taken into account in patients with repeatedly cough, expectoration and fever after anti-infection treatment and solid or cystic lesion in CT image. Contrast enhanced CT/MRI is helpful in PS diagnosis.
