An Incidental Uptake of 18F-Choline at PET/CT in Gastric Neuroendocrine Tumor

Clin Nucl Med. 2021 Apr 1;46(4):e238-e239. doi: 10.1097/RLU.0000000000003289.

Abstract

We present a case of neuroendocrine tumor localized in the gastric mucosa, incidentally detected by 18F-choline PET/CT in a 69-year-old man with prostate cancer. 18F-choline PET/CT scan showed an increased activity in the stomach, later diagnosed as a well-differentiated neuroendocrine tumor, at biopsy. A careful attention of reading 18F-choline PET/CT images should be made, in order to avoid the missing of potential concomitant neoplasia in patients with prostate cancer.
