Trans-mediastinal herniation of lung is seen occasionally but herniation of bulla across the mediastinum is rare. We report two cases with trans-mediastinal herniation of bullae leading to an unusual line appearing near the mediastinum. We propose the name 'Semilunar sign'for this radiological sign because of its resemblance to the half-moon shape.
肺的经纵隔疝偶尔可见,但肺大疱经纵隔疝罕见。我们报告两例肺大疱经纵隔疝,导致纵隔附近出现一条不寻常的线。由于其类似半月形,我们为此影像学征象提出“半月征”这一名称。
