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

Clin Nucl Med. 2018 Dec;43(12):e468-e470. doi: 10.1097/RLU.0000000000002295.

Abstract

In 2 high-risk prostate cancer patients, PET scans revealed focally increased Ga-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 Ga-prostate-specific membrane antigen PET/CT, and these cases present this phenomenon in the esophagus as well.
