    INPUT: There are findings consistent with thoracotomy and a right chest tube is present . Linear density projecting over the right lung may represent an epidural catheter and is similar in appearance . Again seen is a small right effusion , minimally larger , with atelectasis at the right lung base . No pneumothorax is detected . The cardiomediastinal silhouette is grossly unchanged . The possibility of slight rightward shift of the mediastinum can not be excluded . There is mild vascular plethora , without overt CHF . On the left , no focal consolidation is identified . There is a small left pleural effusion , essentially unchanged , with minimal left base atelectasis . No left - sided pneumothorax .
    OUTPUT:
    
1 . Small right effusion , with elevated right hemidiaphragm and underlying atelectasis . Probable slight right which shift of mediastinum , unchanged . No frank consolidation detected . 2 . Mild vascular plethora , without overt CHF . 3 . No pneumothorax detected in either lung . Thoracotomy changes on the right side , with right chest tube noted . 4 .
