Figure 1. In A, CT scan of the chest with lung window settings at the level of the upper lobes, showing nodules and a thick-walled cavity in the right upper lobe. On the left, note a large cavitary lesion and an intracavitary mass, with air interposed between the mass and the cavity wall (the air crescent sign). In B, CT scan of the chest with mediastinal window settings after administration of intravenous contrast, showing intense enhancement of the intracavitary mass, consistent with a diagnosis of aneurysm formation (Rasmussen’s aneurysm).
