    INPUT: Frontal and lateral radiographs of the chest were acquired . A right PICC is seen terminating within the mid-to - low SVC , not significantly changed . A left - sided pacemaker with associated right atrial , right ventricular , and left ventricular leads is unchanged in appearance . A moderate left pleural effusion is increased while a small right pleural effusion is unchanged . There is left lower lung compressive atelectasis , although concomitant infection at the left base can not be excluded . There is no overt pulmonary edema , although the hila appear engorged . Moderate cardiomegaly is not significantly changed . There is no pneumothorax . Multilevel degenerative changes of the thoracolumbar spine are seen .
    OUTPUT:
    
1 . Appropriately positioned right PICC , with tip in the mid-to - low SVC . 2 . Increased left pleural effusion and left lower lung atelectasis . Concomitant infection at the left lung base can not be excluded . 3 . Unchanged small right pleural effusion . 3 . Unchanged moderate enlargement of the cardiac silhouette .
