Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is probably at the upper limits of normal size . There is moderate tortuosity of the aorta and the archs shows patchy calcification , as before . Calcified lymph nodes in the right hilum and in the right lower paratracheal region suggest prior granulomatous exposure . A trace right - sided pleural effusion is suspected . A small effusion is difficult to exclude on the left . There is new mild relative elevation of the left hemidiaphragm . The lung volumes are low . There is new perihilar fullness as well as indistinct prominent pulmonary vascularity with a mild interstitial process , predominantly in the mid lungs , suggesting mild vascular congestion . A band - like opacity in the left upper lobe shows a slightly altered morphology and may account for by a nodular density measuring up to ___ x 4 mm as imaged in the coronal plane by radiography , although a new nodule is possible and it may even correlate with a newly apparent posterior nodular opacity in the lateral view projecting over the mid to lower thoracic spine . Patchy basilar opacities suggest additional areas of minor atelectasis . The bones are probably demineralized . There is similar exaggerated kyphotic curvature at the thoracolumbar junction with mild degenerative changes .
    OUTPUT:
    
1 . Findings suggesting mild vascular congestion . 2 . Possible nodule in the left mid lung ; evaluation with chest CT is recommended when clinically appropriate .
