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.

Figure 3: Case 2: Chest X-ray reveals bilateral upper zone fibrotic lesions, small left hydropneumothorax and a thin line across the left hilum (arrows)

Mentions: His chest X-ray revealed bilateral upper zone fibrotic lesions, small left hydropneumothorax and a thin line across the left hilum [Figure 3]. CT of the chest revealed a bulla in the right lung extending across the mediastinum below the sternum [Figure 4], left sided hydropneumothorax and a pleural based lung mass in left lower lobe. The compressed parenchyma and pleura of both the sides was responsible for the line appearing on the chest X-ray. Subsequently CT-guided fine needle aspiration (FNAC) of the left lung lesion revealed bronchogenic carcinoma. The patient received chemotherapy for bronchogenic carcinoma. He partially responded to the chemotherapy.
