    INPUT: PA and lateral views of the chest are obtained . The previously seen right juxtahilar opacification is demonstrated on this study and while it could possibly represent right lower lobe atelectasis with associated right pleural fluid , a right hilar mass is possible . There is elevation of the right lung base . There is also some left basilar atelectasis which is again seen . Two drainage catheters are unchanged in position overlying the mid abdomen .
