Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral chest views were obtained with patient in upright position . Analysis is performed in direct comparison with the next preceding similar study of ___ . The heart size remains within normal limits . Similar as identified on previous examination , there exists extensive pericardial calcifications surrounding the ventricular contours , but excluding the atrial wall areas . The pulmonary vasculature is not congested . Slightly prominent azygos vein suggests elevated venous pressure . This existed already on the previous study . The pulmonary vasculature is not congested . There exists now a moderate amount of pleural effusion on the right base that obliterates the lateral pleural sinus and obscures the peripheral half of the right - sided diaphragm . The fluid extends along the right lateral chest wall and reaches the minor fissure . When the lateral views are compared , increase of pleural density in the posterior pleural sinus and along the posterior pleural space has increased markedly and the amount must now be considered to be moderate . As the films were obtained following a recent thoracocentesis , it can be assumed that the right - sided pleural effusion was markedly increased since the preoperative chest examination of ___ . Comparison with the most recent chest CT of ___ , indicates that the present pleural effusion has a similar extension at that time .
    OUTPUT:
    
No evidence of pneumothorax status post right - sided thoracocentesis . Pleural effusion similar to what was present on chest CT of ___ .
