tree in bud lesion

The tree-in-bud sign is a nonspecific imaging finding that implies impaction within bronchioles the smallest airway passages in the lung. Centrilobular nodules with a linear branching pattern are consistent with tree-in-bud appearance in a patient with endobronchial spreading of post-primary tuberculosis.
