气管支气管憩室的诊断进展

Advances in diagnosis of tracheal and bronchial diverticulum

气管支气管憩室是一种少见的良性气管疾病，气管憩室多数位于胸廓人口处气管右后侧，表现为圆形或卵圆形囊泡，内含气体或液体。近年来，随着薄层CT及多层螺旋CT的应用，气管支气管憩室的报道日趋增多，该文综述了气管支气管憩室分类及诊断治疗进展。

Tracheal and bronchial diverticulum is a rare benign entity, characterized by round or spherical outpouchings of the tracheal and bronchial wall. Tracheal diverticulum is commonly seen on right side, containing air or fluids. The development of new techniques such as thin-layer CT and multidetector computed tomography have led increasingly reports of incidental findings of this entity. This paper reviews the classification, diagnosis and therapy of this entity.
