Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Right - sided Port - A - Cath tip terminates in the SVC . Large right pleural effusion which is loculated appears slightly increased compared to the prior study . Right basilar opacification could reflect compressive atelectasis though infection is not excluded . Chest tube is again noted with tip projecting over the right lung base . There is mild leftward shift of mediastinal structures , slightly increased compared to the prior study . Cardiac and mediastinal contours otherwise are unchanged . Streaky left basilar opacity likely reflects atelectasis . No pneumothorax is identified , and no pulmonary edema is seen . No acute osseous abnormalities detected .
    OUTPUT:
    
Large right loculated pleural effusion , slightly increased in size with increasing right basilar opacification suggestive of atelectasis though infection is not excluded .
