Trans-mediastinal herniation of bulla: Semilunar sign.

Singh S, Singh N, Singh V - Lung India (2015 Nov-Dec)

Bottom Line: 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.

ABSTRACT
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.

Case 1: CT chest shows a giant bulla in the right lung extending across the mediastinum below the sternum. The compressed pleura (arrow) produced the semilunar-shaped line on the radiograph

Figure 2: Case 1: CT chest shows a giant bulla in the right lung extending across the mediastinum below the sternum. The compressed pleura (arrow) produced the semilunar-shaped line on the radiograph

Mentions: His chest X-ray revealed hyperinflated lung fields, left upper zone fibrocalcified lesion and a thin line extending from left upper zone to middle zone [Figure 1]. His computed tomography (CT) of the chest revealed a bulla in the right lung extending across the mediastinum below the sternum [Figure 2]. The compressed pleura produced the thin line on the radiograph and we propose the name ‘Semilunar sign’ for the same. Forceful coughing and daily physical strain were probably responsible for the emphysematous bulla to herniate across the mediastinum.
