Figure 2

A 70-year-old woman (case 1). (a) Chest CT performed immediately after her arrival at our hospital (60 min after the estimated CAE onset). There is a giant bulla (8 cm in diameter) with septa in the left upper lobe. (b) Chest CT scan obtained 10 days after her admission shows collapse of the bulla with fluid collection (arrow) and thickening of the septa (arrow heads).
