    INPUT: Single portable frontal image of the chest . The lung volumes are low . There has been interval development of a linear opacity in the left mid lung which likely represents subsegmental atelectasis , probably in the lingula . A calcified granuloma is seen in the medial right lung base . Opacity is seen in the medial right lung base , which may refelect a combination of atelectasis and overlapping vascular structures . There is patchy atelectasis at the left lung base . There is a small right pleural effusion . A feeding tube is noted in adequate position in the stomach . There is no pneumothorax . The cardiomediastinal silhouette is mildly enlarged but stable from prior exam .
    OUTPUT:
    
Left basilar atelectasis and small right effusion . Opacity at medial right lung base , which may refelect a combination of atelectasis and overlapping vascular structures . This could be better assessed on follow - up radiographs .
