Pulmonologist performed bronchcopscopy and lavage and reported he removed a lot of pus. Where would pus have formed and what condition would have caused this? CT Scan taken before procedure indicated interval development of pre-existing bronchiectasis most prominently in right middle lobe with adjacent reticulonodular and tree-in-bud opacities in the right middle lobe andright lower lobe which are new since prior study. There is interval development of a lingular bronchiectasis with some adjacent consolidation. There is also mild right lower lobe bronchiectasis medially. There is mild bronchiectasis and peribronchial opacities in the inferior right upper lobe on images 48-52. There is a stable 5 mm right upper lobe nodule unchanged since 9/30/2003, indicating benign etiology. There is a stable 4 mm groundglass opacity in the posterior left lower lobe on image 62 which is unchanged since 7/27/2007. There are no new parenchymal lesions.
