Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral chest views have been obtained with patient in upright position . There is a sizeable left - sided pleural effusion that obliterates the diaphragmatic contour and the lateral portion of the heart shadow . Heart size can not be accurately assessed , but is probably within normal limits as there is no evidence of pulmonary congestion . A right - sided Port - A - Cath system introduced via the right internal jugular vein approach is seen to terminate in the lower third of the SVC close to the expected entrance into the right atrium . No pneumothorax can be identified . There is evidence of bilateral pleural effusion , more so on the left than the right , where the effusion just blunts mildly the right lateral and right posterior pleural sinuses . On the left side , the pleural effusion reaches along the left lateral wall up to the hilar level . There is no pneumothorax on either side . Our records do not include a previous chest examination available for comparison .
    OUTPUT:
    
Heart size can not be assessed because of left - sided pleural densities obliterating the contours . Small amount of pleural effusion also seen on right side . Port - A - Cath system in place . No pneumothorax . Moderate gas distention of stomach . No evidence of acute pulmonary vascular congestion or infiltrates or masses . A page call was rendered on specific request for #___ at 5 :20 p .m . Contact with the house officer was established and the findings reported . An estimate is that the left - sided pleural effusion may contain up to 500 mL .
