    INPUT: In the interval since the prior study , there has been development of large posterior right upper lobe opacity . Findings are concerning for pneumonia . In the prior chest CT from ___ , a 14 mm spiculated nodule is seen in the posterior right upper lob ; conceivable but much less likely , there may have been quite significant growth of the nodule in the interval . Also , correlate with any history of intervening procedure . Right paratracheal opacity with leftward indentation of the trachea is consistent with patient 's known enlarged right lobe of the thyroid . No large pleural effusion is seen in the small amount of pleural fluid along the right lung apex is difficult to exclude . There is no evidence of pneumothorax . The aorta is calcified and slightly tortuous . The cardiac silhouette is not enlarged . There is no overt pulmonary edema .
    OUTPUT:
    
Large posterior right upper lobe opacity is concerning for pneumonia . On prior chest CT from ___ , a 14 mm spiculated nodule is in the posterior right upper lob ; conceivable but much less likely quite significant growth of the nodule in the interval . Also , correlate with any history of intervening procedure . The large posterior right upper lobe opacity was not seen on chest radiograph from ___ . Right paratracheal opacity with leftward deviation of the trachea again seen , consistent with patient 's known enlarged right lobe of thyroid .
