Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A right - sided internal jugular Port - A - Cath terminates in the mid SVC . The cardiomediastinal contour is unchanged compared to the prior study with borderline cardiomegaly . Previous median sternotomy noted and calcification aortic arch . There are peripheral subpleural reticular opacities at the lung bases suggestive of interstitial lung disease . This is similar in appearance when compared to the prior study . No pneumothorax or pleural effusions seen . Minimal right basilar atelectasis . There has been prior aortic valve replacement . The bones are diffusely demineralized .
    OUTPUT:
    
Overall appearances are very similar when compared to the prior study . Peripheral reticular opacities of the lung bases are difficult to evaluate and further evaluation with CT of the chest could be performed if there is concern for interstitial lung disease .
