    INPUT: Cardiac silhouette size is normal . The aorta is tortuous . Mediastinal and hilar contours are unchanged . The pulmonary vasculature is not engorged . Previously noted small right apical pneumothorax is not clearly visible on the current exam . Patchy opacity within the right lower lobe corresponds to the known lesion which was recently biopsied . Subsegmental atelectasis is seen in the left lung base . No focal consolidation or pleural effusion is detected . There are no acute osseous abnormalities .
    OUTPUT:
    
Previously noted small right apical pneumothorax is not clearly seen on the current exam and likely has resolved . Patchy right basilar opacity corresponding to the known right lower lobe lesion is better assessed on the previous CT .
