Fig. 1.

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). .
