Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single portable view of the chest . Left PICC is seen with tip in the mid SVC . There is an opacity projecting over the anterior right 2nd rib , potentially related to osseous structures however underlying parenchymal changes are also possible . The lungs are otherwise grossly clear . The descending thoracic aorta is tortuous and may account for apparent left hilar enlargement . There is however possible right hilar enlargement as well . Cardiac silhouette is enlarged even given technique . No acute osseous abnormality detected .
    OUTPUT:
    
No definite acute cardiopulmonary process . Possible hilar enlargement , particularly on the left . This appearance could partially be accounted for by a tortuous descending thoracic aorta . Dedicated chest x-ray with 2 views is suggested to further characterize this finding and apparent increased opacity projecting over the anterior right 2nd rib as well .
