Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Right - sided Port - A - Cath tip terminates in the proximal right atrium , newly placed in the interval . The heart remains moderately enlarged . Low lung volumes are present which cause crowding of the bronchovascular structures . There may be mild pulmonary vascular congestion but no overt pulmonary edema is identified . Mediastinal contour is unchanged . Assessment of the lung apices is obscured due to the patient 's neck soft tissues projecting over these regions . Again demonstrated , however , is opacification within the left apex corresponding to the known mass in this location . The known right lower lobe pulmonary nodule is not as well assessed on the current exam . Streaky atelectasis is demonstrated in the left lung base . No pleural effusion or large pneumothorax is identified . Pneumoperitoneum is new in the interval .
    OUTPUT:
    
1 . New pneumoperitoneum . 2 . Low lung volumes cause crowding of the bronchovascular structures with possible mild pulmonary vascular congestion . No overt pulmonary edema . 3 . Re - demonstration of left apical mass , though assessment is limited . Known right lower lobe nodule is not well visualized on the current exam .
