Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Again seen is a round opacity in the left upper lobe which corresponds to the laceration seen on the prior CT . This is unchanged compared to the prior exam . The left third rib fracture is not clearly seen on this exam . The previously noted right upper lobe nodules on the CT also can not be clearly seen on this exam . No new focal consolidations are identified in the lungs . The mediastinal and hilar borders are unremarkable . There appears to be interval increase in the left - sided pleural effusion ; however , this may be secondary to differences in patient positioning compared to the prior exam . There is stable moderate cardiomegaly .
    OUTPUT:
    
1 . The comminuted lateral third rib left fracture well seen on prior CT is not seen clearly on this exam . If absolutely clinically necessary , would recommend CT for further evaluation . 2 . There appears to be an interval increase in the left - sided pleural effusion , however , the differences may be secondary to patient positioning technique .
