A 46-year-old man was transferred to our hospital due to an unexpandable lung after a closed thoracostomy for his spontaneous pneumothorax (Fig. 1A and B). His chest computed tomography (CT) scans showed a cavitary consolidation in the left upper lobe and micronodules in the right upper lobe (Fig. 1C). His left lung showed structural changes including emphysema and hypoplasia (Fig. 1C). Incidentally, left pulmonary artery agenesis was noticed in his CT scans (Fig. 1D).
