    INPUT: Previously seen areas of multifocal consolidation on chest radiograph from ___ have resolved . Diffuse interstitial opacities persist and appear to have progressed since the prior chest radiographic examination . In the absence of hilar enlargement , cardiomegaly , and pleural effusions , these increasing interstitial opacities may reflect worsening chronic fibrosis or superimposed atypical infection . No confluent consolidation is identified . Cardiomediastinal and hilar contours are unchanged . Calcified pleural plaques are again noted . Surgical clips are seen within the right upper quadrant . Compression deformity of the lower thoracic spine is similar to recent trauma torso CT . Incidental note is made of calcifications in the region of the left carotid artery .
    OUTPUT:
    
Reticular opacities which may reflect progressive lung fibrosis or superimposed infection . Pulmonary edema seems less likely given the lack of associated features .
