27-year-old African-American male with late-onset cystic fibrosis. Axial views of contrast-enhanced reformatted chest CT. A) Localized dilation of the bronchi reveals upper-lobe bronchiectasis (arrow). Peribronchial cuffing demonstrates extent of inflammation and mucous impaction. B) Tree-in-bud opacities appear within the lungs (arrow). Note the narrowed mediastinum.

A chest CT revealed predominantly upper-lobe bronchiectasis, with diffuse tree-in-bud opacities (Fig. 4).
27-year-old African-American male with late-onset cystic fibrosis. Axial views of the abdomen from contrast-enhanced chest CT. A) The target sign is seen within the small bowel, indicating transient intussusception (arrow). The large bowel is dilated with severe fecal impaction (arrowheads). B) Diffusely atrophic pancreas (arrows) is noted anterior to the left kidney demonstrating hyperattenuation secondary to fatty replacement. Also note decreased liver attenuation (L) as compared to the spleen (S).

Although the patient did not have gastrointestinal complaints, transient intussusception of the small bowel was noted as well as dilation and severe fecal impaction within the large bowel (Fig. 5A). The pancreas was diffusely atrophic and showed marked fatty replacement (Fig. 5B).
