Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Left - sided Port - A - Cath tip terminates at the junction of the SVC and right atrium . Lung volumes are low . Heart size is accentuated as a result appearing mildly enlarged . Mediastinal contour is similar . The hilar contours are unremarkable . Crowding of bronchovascular structures is present without overt pulmonary edema . There are patchy opacities in the lung bases , potentially atelectasis in the setting of low lung volumes . Previously described nodules seen on chest CT are not visualized on the current exam . No large pleural effusion or pneumothorax is present . There are no acute osseous abnormalities .
    OUTPUT:
    
Limited study as result of low lung volumes . Patchy opacities in the lung bases may reflect atelectasis but infection or aspiration can not be excluded in the correct clinical setting .
