Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A left - sided PICC terminates in the proximal SVC . There is diffuse increase in interstitial markings bilaterally which may be due to moderate pulmonary edema and / or atypical infection . A more focal opacity is seen in the lateral right lower lung , which could also relate to infection . There is prominent right apical thickening . No large pleural effusion or pneumothorax is seen . The cardiac silhouette is top - normal . The aorta is tortuous . The partially imaged humeral heads are high riding , which can be seen in rotator cuff disease .
    OUTPUT:
    
Diffuse increase in interstitial markings bilaterally could be due to pulmonary edema , atypical infection , or related to chronic lung disease ; no prior chest radiographs available for comparison . More focal opacity at the lateral right lung base could be due to infection . Prominent right apical thickening , possibly pleural ; recommend comparison with remote prior chest radiographs to assess for chronicity , otherwise , followup outpatient chest CT for further assessment .
