Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral chest views were obtained with patient in upright position . The heart size is within normal limits . No typical configurational abnormality is identified . Thoracic aorta unremarkable . The pulmonary vasculature is not congested . The diaphragms are in relatively low position and somewhat flattened . This coincides with increased translucency on the lung bases and somewhat irregular peripheral pulmonary vasculature . In the mid portion of the left hemithorax , some scattered parenchymal infiltrates are noted laterally to the hilum and most likely represents some scattered pneumonic infiltrates . The left lateral and posterior pleural sinus is free . In the right hemithorax , a remarkable prominent and dense breast shadow is noted clearly , much larger than the breast on the left side . Although this finding obscures somewhat the lung fields , there is no conclusive evidence for any acute infiltrate . Noted , however , is a mild blunting of the right lateral pleural sinus . When comparison is made with the next previous chest examination of ___ , heart size configuration is unchanged . The at that time existing pneumonic infiltrate in the posterior segment of the left lower lobe has disappeared . The now present scattered infiltrates in the mid lung field in the left hemithorax , however , are new . Also new is the blunted right lateral pleural sinus and comparison also demonstrates that the low positioned diaphragm and general findings of emphysema in the bases have developed since the next preceding study .
    OUTPUT:
    
Scattered pulmonary infiltrates in the mid lung field of left hemithorax . New pleural blunting on the right base . Markedly prominent right - sided breast shadow . Followup examination is recommended . Also , clinical comparison of the unusual right - sided breast shadow is recommended .
