Nov 27, 2025 · Centrilobular nodules can be observed in a wide variety of lung pathology. In particular, pathologies involving the bronchioles and the arterioles (i.e., bronchiolitis and vasculitis), as both are …

Multiple centrilobular nodules, many with a tree in bud type configuration, with minor ground glass opacity are identified involving primarily the lateral aspect of the left lower lobe.

CT confims numerous centrilobular nodules with opacified distal bronchioles (tree-in-bud sign) and bronchiectasis. These findings most likely represents pulmonary TB or MAC despite negative …
