BACKGROUND Multiple causes for tree-in-bud TIB opacities have been reported. Tree in bud opacification refers to a sign on chest CT where small centrilobular nodules and corresponding small branches simulate the appearance of the end of a branch belonging to a tree that is in bud. A Thin-section CT scan of the right lung shows centrilobular ground-glass opacities in addition to nodules and tree-in-bud opacities arrow.

The tree-in-bud pattern suggests active and contagious disease especially when associated with adjacent cavitary disease within the lungs. Multiple causes for tree-in-bud TIB opacities have been reported. There is a new cluster of tree in bud opacities in the right middle love with minimal uptake above background which is almost certainly infectiousinflammatory.

Other noninfectious conditions that produce bronchiolar impaction and a tree-in-bud. TIB opacities are also associated with bronchiectasis and small airways obliteration resulting in mosaic air trapping. A tree-in-bud pattern of centrilobular nodules from metastatic disease occurs by two mechanisms.
