    INPUT: There is extensive posterior spinal stabilization hardware in - situ , incompletely visualized . This partially obscures the tracheostomy tube which is grossly unchanged in position . A left - sided PICC terminates in the azygos vein as seen on multiple prior studies . There is persistent left lower lobe atelectasis and a hazy opacity at the right lung base likely reflecting layering of a pleural effusion which is increased compared to the prior study . There is also a right lower lobe atelectasis . Prominence of the pulmonary vasculature may reflect a degree of fluid overload .
    OUTPUT:
    
Probable increase in the right pleural effusion with associated compressive atelectasis . The left - sided PICC terminates in the azygos vein , unchanged compared to multiple prior studies .
