Case Notes

Cystic fibrosis is a hereditary disease that leads to neutrophilic inflammation in the lung airways, providing a backdrop for frequent infections to develop.

In FDG PET/CT, increased F-18 FDG uptake can be observed in the airways accompanied by bronchiectasis. Studies in the literature have shown a decrease in SUVmax values after treatment.
