Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The inspiratory lung volumes are decreased from the most recent prior study . Mild blunting of the left costophrenic angle may be related to atelectasis and , less likely a small left pleural effusion . Increased streaky opacification of the left heart border likely represents left basilar atelectasis . No right pleural effusion is detected . No pneumothorax is identified . Mild pulmonary vascular congestion is noted . The cardiac silhouette is mildly enlarged , which is accentuated in the setting of low lung volumes but likely stable allowing for differences in AP technique and low lung volumes on today 's examination compared to the prior study . The thoracic aorta is slightly tortuous . The trachea is midline . There is no evidence of free air beneath the right hemidiaphragm . Note is made of a density projecting over the inferior right hilum , which is not seen on the prior study . The azygos vein appears prominent .
    OUTPUT:
    
1 . Mild pulmonary vascular congestion . 2 . Enlargement of the cardiac silhouette is likely unchanged from the prior study allowing for differences in technique and lower lung volumes . 3 . Right inferior hilar density measuring approximately 2 .3 cm for which additional imaging on a non-urgent basis is recommended with dedicated PA and lateral chest radiographs possibly followed by cross-sectional imaging . The patient was admitted and the above findings were discussed by Dr . ___ with Dr . ___ ___ internal medicine via telephone at 4 :30 PM on ___ .
