Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiomediastinal and hilar contours are stable . A right - sided dual - lumen central venous catheter tip terminates within the proximal right atrium and at the junction of the SVC and right atrium , as before . Moderate cardiomegaly is re - demonstrated . The pulmonary vasculature is within normal limits . A moderate left - sided pleural effusion is minimally decreased in size from the prior examination . Left basal opacity is again demonstrated . The tip of a percutaneous gastrostomy catheter is noted in the left upper quadrant of the abdomen . No pneumothorax . There is irregular lucency and compression deformity of the right humeral head , suggestive of sever degenerative changes with possible avascular necrosis .
    OUTPUT:
    
Left - sided pleural effusion is minimally decreased in size from the prior examination . Persistent left basal opacity may represent compressive atelectasis ; however , infection should be considered in the appropriate clinical setting . Irregular lucency and compression deformity of the right humeral head , suggestive of sever degenerative changes with possible avascular necrosis . Recommend clinical correlation .
