Rahbar K Shi X et al 2017 Pulmonary tuberculosis. Tree-in-bud TIB is a radiologic pattern seen on high-resolution chest CT reflecting bronchiolar mucoid impaction occasionally with additional involvement of adjacent alveoli. It consists of small centrilobular nodules of soft-tissue attenuation connected to multiple branching linear structures of similar caliber that originate from a single stalk.
