Abstract
A 53-year-old man with persisting increased serum prostate-specific antigen level (9.53 ng/mL) and repeated negative prostate biopsies was referred for a PET/CT with 68 Ga-PSMA-11. The PET/CT revealed focal uptake in the prostate suggestive of localized prostate cancer. Incidentally, it also showed a diffuse uptake in the tracheobronchial tree suspicious for a benign etiology. Because of the clinical history of asthma exacerbation in the previous week, further supplementary studies were performed showing a pathological fractional exhaled nitric oxide level (92 ppb; reference values, <25 ppb) and mild airway obstruction in the spirometry. These findings confirmed asthma as an inflammatory etiology of the tracheobronchial PSMA uptake.
