Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Widening of the mediastinum , particularly the right mediastinal contour is due to a large infiltrative mediastinal mass , better assessed on the prior CT performed the same day . A right apical mass is also demonstrated . A large right pleural effusion with right basilar opacity compatible with atelectasis is again seen . Small left pleural effusion is noted . There is mild prominence of the interstitial markings within the left lung which could suggest mild volume overload . No pneumothorax is identified . Heart size is difficult to assess given the presence of the large right pleural effusion . Numerous compression deformities are seen within the imaged thoracolumbar spine , better assessed on the CT . Remote right - sided rib fractures are present .
    OUTPUT:
    
Large mediastinal mass and right apical mass compatible with malignancy . Large right pleural effusion and small left pleural effusion with associated right basilar atelectasis . Possible mild fluid overload . Numerous compression fractures within the imaged thoracolumbar spine .
