Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Right - sided Port -A - Cath is in unchanged position . There is a moderate to large right - sided hydro-pneumothorax seen predominantly at the right base status post recent thoracentesis . The amount of right pleural fluid is markedly decreased . A small to moderate left - sided pleural effusion is minimally increased . Adjacent pulmonary opacity likely reflects compressive atelectasis . Opacity at the base of the right lung likely reflects atelectasis .
    OUTPUT:
    
Moderate right hydro pneumothorax seen at the base of the right lung is demonstrated however the amount of right pleural fluid is markedly decreased , reflecting invertal thoracentesis . Moderate left effusion is minimally increased . Pulmonary opacities at the bases likely reflects atelectasis or mild edema .
