Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Left - sided Port - A - Cath terminates in the proximal to mid SVC without evidence of pneumothorax . No priors available for comparison . There is volume loss of the left lung . Left base opacity is seen which may be due to infection , aspiration , chronic change , related to patient 's known lung cancer . Left apical opacity could be due to pleural fluid , chronicity unknown . No focal consolidation , pleural effusion , or pneumothorax is seen on the right . Cardiac silhouette is top - normal . Left paratracheal opacity is seen , unclear whether this relates to patient 's pulmonary malignancy . Comparison with prior studies would be helpful for further assessment .
    OUTPUT:
