肺隔离症(PS)是一种罕见的先天性肺发育畸形,无正常肺功能,患者主要临床表现为咯血、咳嗽、咳痰、发热、胸痛等.PS为临床少见病,而由于其临床表现缺乏特异性、常规影像学检查较难与其他肺部疾病鉴别,故易误诊、漏诊.本文报道了1例经增强CT+三维重建及结合临床表现确诊的PS患者,并结合文献对PS的临床表现、病理特点、诊断、治疗等进行复习,以期提高临床医生对该病的认识.%Pulmonary sequestration is one kind of rare congenital pulmonary developmental deformity without normal pulmonary function,mainly performed as hemoptysis,cough,expectoration,pyrexia,chest pain and so on.Pulmonary sequestration is uncommon on clinic,lacking specific clinical manifestation and is difficult to identify with other pulmonary disease according to routine imaging examination,thus easily results in misdiagnosis and missed diagnosis.This paper reported a case with pulmonary sequestration that confirmed by enhanced CT combined with three-dimensional reconstruction based on clinical manifestation,reviewed the related literatures to summarize the clinical manifestation,pathologic feature,diagnosis and treatment of pulmonary sequestration,in order to improve the understanding of clinicians.
