The inferior pulmonary ligament, a double layer of pleura that tethers the lower lobe of the lung to the mediastinum, is rarely appreciated on plain radiographs but may be involved in pathologic processes. A linear structure on axial computed tomographic (CT) images of the lung bases corresponds to the inferior pulmonary ligament on cadaver sections. Review of 100 CT studies identified at least one inferior pulmonary ligament in 42%. Its presence and configuration did not correlate with patient age or gender. The anatomy and CT appearance of the ligament are discussed.
肺下韧带是一层双层胸膜，将肺下叶与纵隔相连，在普通X线片上很少能被发现，但可能参与病理过程。肺底部轴向计算机断层扫描（CT）图像上的线性结构与尸检切片上的肺下韧带相对应。回顾100例CT研究发现，42%的病例至少有一条肺下韧带。其存在和形态与患者年龄或性别无关。本文讨论了该韧带的解剖结构和CT表现。
