Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Right sided PICC tip terminates in the mid SVC . The patient is status post median sternotomy and closure hardware with CABG clips . Heart size is mildly enlarged but unchanged . The aorta is diffusely calcified and tortuous . Blunting of the left costophrenic angle is compatible with a small pleural effusion , decreased in extent compared to the prior exam . Small right pleural effusion also appears smaller compared to the prior exam . Streaky left basilar opacity likely reflects atelectasis . There is no pneumothorax , though the patient 's chin slightly obscures evaluation of the extreme lung apices . No pulmonary vascular congestion is seen . Right curvilinear subdiaphragmatic lucency is compatible with pneumoperitoneum , which is not unexpected in this patient on peritoneal dialysis .
    OUTPUT:
    
1 . Curvilinear right subdiaphragmatic lucency likely reflects pneumoperitoneum which is not unexpected in this patient who is on peritoneal dialysis . 2 . Decreased in size of small bilateral pleural effusions . Minimal left basilar atelectasis .
