Cavitary lesion with decreased lung parenchymal volume is seen at right upper lobe. Alveolar opacity is noted at lingula segment of left upper lobe. Centrilobular nodules with a linear branching pattern are also seen at both lung parenchyma.
Case Discussion
Centrilobular nodules with a linear branching pattern are consistent with tree-in-bud appearance in a patient with endobronchial spreading of post-primary tuberculosis.
