    INPUT: Compared to prior study there appears to be worsening of the left - sided opacification which appears to be within nearly the entire left lung with obliteration of the left heart border and left hemidiaphragm . There is a small focus of relative hyperlucency in the left cardiophrenic angle compared to the rest of the lung and may represent a small , loculated pneumothorax . The orogastric tube has been removed . There is otherwise no change compared the prior study with persistent pulmonary edema . A right dual lumen dialysis catheter is unchanged in position . Remnant of a left - sided dialysis catheter is unchanged in position with a small piece of the tip broken off and lodged in a distal left pulmonary artery , unchanged . There is no pneumothorax . Endotracheal tube remains in place in appropriate position .
    OUTPUT:
    
Interval worsening of left lung opacification which may be due to progressive pneumonia or worsening edema . An underlying lung mass can not be excluded . Relative lucency of the left costophrenic angle is suggestive of a loculated pneumothorax .
