case 1. The upper lobe of the right lung is completely collapsed, but the middle and lower lobes are almost completely expanded, and an air space in the right pleural cavity has appeared around the atelectasis of the upper lobe (A). A calcified mass (red arrowhead), which is suggestive of a foreign body, is observed in the lumen of the right upper bronchus (B). Bronchoscopy reveals obstruction of the bronchial lumen of the upper lobe bronchus by the rice grains (C). After removal of the rice grains, the right upper pulmonary lobe has expanded completely, with some pulmonary edema (D). .

case 2. The middle and lower lobes of the right lung are completely collapsed, but the upper lobe is almost completely expanded, and an air space in the right pleural cavity has appeared around the collapsed lobes (A). The right intermediate bronchial trunk is obstructed by sputum (red arrowhead) (B). Bronchoscopy reveals obstruction of the bronchial lumen by viscous sputum (C). After the bronchoscopic removal of sputum, atelectasis of the middle and lower lobes improves, and the air space in the right pleural cavity almost disappears (D). .

Chest CT revealed a complete pulmonary collapse of the middle and lower lobes of the right lung, an almost complete expansion of the upper lobe, and a mediastinal shift to the affected side (Fig. 2).
