Benign Esophageal Findings on 68Ga–Prostate-Specific Membrane Antigen PET/CT Scan

In 2 high-risk prostate cancer patients, PET scans revealed focally increased 68Ga–prostate-specific membrane antigen uptake in the distal esophagus. Both patients had hiatus herniation on gastroscopy, and esophageal biopsies revealed acute and chronic inflammation in both patients and a benign hyperplastic polyp in one of the patients. Recently, reports have demonstrated that inflammation can cause false-positive findings on 68Ga–prostate-specific membrane antigen PET/CT, and these cases present this phenomenon in the esophagus as well.
