Tubular bronchiectasis can be seen in the right upper lobe and posterior segment of the right lower lobe, some of which present spontaneously dense endoluminal material (90 HU), which extends from the hilum to the periphery (finger in glove sign). Associated with this, centrilobular nodules can be seen, some of them convergent, with a predominance of the posterior segment of the lower right lobe, conforming to a tree-in-bud pattern. Heterogeneity of densities of the endoluminal material, corresponding to different evolutionary stages of mucous plugs, can be noticed in the mediastinal window.
No hilar or mediastinal lymphadenopathy. No pleural or pericardial effusion.
