Abstract
Tree-in-bud sign refers to the condition in which small centrilobular nodules less than 10 mm in diameter are associated with centrilobular branching nodular structures [1] (Fig. 9.1). The small nodules represent lesions involving the small airways. However, vascular lesions involving the arterioles and capillaries may simulate the centrilobular small nodules and branching nodular structures (vascular tree-in-bud sign) [2–5] (Fig. 9.2).
