High-attenuation mucus in allergic bronchopulmonary aspergillosis

(A) High-resolution CT shows broad tubular opacity in the left lower lobe (arrow) and bronchiectasis in the right upper and lower lobes.

(B) CT image at soft tissue windows demonstrates that the impacted mucus (arrowhead) has greater attenuation than the paraspinal musculature.

(C) HRCT after treatment demonstrates residual bronchiectasis (dashed arrow).

ABPA: allergic bronchopulmonary aspergillosis; CT: computed tomography; HRCT: high-resolution computed tomography.
