The differential diagnosis is lengthy. Tree in bud opacities seen in. Tree-in-bud refers to a pattern seen on thin-section chest CT in which centrilobular bronchial dilatation and filling by mucus pus or fluid resembles a budding tree.

Uncommonly this pattern can be seen in other entities that cause luminal impaction bronchiolar dilatation or wall thickening including cystic fibrosis immune deficiency inflammatory bowel disease and diffuse panbronchiolitis. Usually somewhat nodular in appearance the tree-in-bud pattern is generally most pronounced in the lung periphery and associated with abnormalities of the larger airways. Bronchial cystazygoesophgeal recesstypical location.

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. It is usually visible on standard ct however it is best seen on hrct chest. The tree-in-bud sign indicates bronchiolar luminal impaction with mucus pus or fluid causing normally invisible.

Although initially described in 1993 as a thin-section chest CT finding in active tuberculosis TIB opacities are by. Tuberculosis many infectious organisms can produce this pattern. However in the presence of disease processes which involve the bronchioles ie infectious or inflammatory conditions they can easily be.

In radiology the tree-in-bud sign is a finding on a CT scan that indicates some degree of airway obstruction. High-resolution CT usually reveals small 24-mm centrilobular nodules and branching linear opacities of similar caliber originating from a single stalk Figs 2 3 4. The purpose of this study was to determine the relative frequency of causes of TIB opacities and identify patterns of disease associated with TIB opacities.

The tree-in-bud pattern is commonly seen at thin-section computed tomography CT of the lungs. These findings most likely represents pulmonary TB or MAC despite negative induced sputum specimens. TIB opacities represent a normally invisible branches of the bronchiole tree 1 mm in diameter that are severely impacted with mucous pus or fluid with resultant dilatation and budding of the terminal bronchioles 2 mm in diameter1 photo.
