Beschreibungen/Notizen

• Prostate-specific membrane antigen (PSMA) PET/CT is a well-acclaimed imaging modality for prostate cancer (PCa). However, many reports have highlighted PSMA radioligand uptake in a variety of benign tumors and lesions. We report a case of PCa in which 68  Ga-PSMA-11 uptake was noted in the tracheal lumen. However, 18 F-PSMA-1007 PET/CT was done on a subsequent day, which demonstrated no abnormal radiotracer uptake or morphological lesion within the tracheal lumen. This case highlights an uncommon finding of PSMA ligand uptake in a tracheal mucus plug (non-prostatic benign uptake), which may be misinterpreted as a false-positive finding.
