. Tree-in-bud pattern seen on high-resolution CT HRCT indicates dilatation of bronchioles and their filling by mucus pus or fluid. There is a cavitating lesion and typical tree-in-bud appearance. Thin section CT shows peribronchial thickening and centrilobular nodules with tree in bud appearance.
These characteristically result in clustersofill-definednodules attached to adjacent branching or tubular structures due to extensive bronchiolar mucoid impac-tion. Less often an airway disease associated primarily with mucus retention like allergic bronchopulmonary aspergillosis and asthma. Bronchial wall thickening aspirated material in the trachea or bronchi and the presence of a hiatal hernia are other clues to the diagnosis.
