[68Ga]Ga-PSMA-11 PET\/CT detected an extensive area of increased tracer uptake at the prostatic level, involving both lobes. Additionally, a rounded lesion approximately 4 cm in diameter was identified in the celiac region adjacent to the stomach, exhibiting moderate tracer uptake. Based on these imaging findings, the patient underwent radiation therapy applied to the prostate and pelvis and a biopsy of the suspected lesion adjacent to the stomach, which was positive for Siewert type III gastroesophageal junction adenocarcinoma (HER2-negative, PDL-1 60%). This case demonstrates the importance of not overlooking incidental tracer uptakes in PSMA PET\/CT imaging in the stomach, as they could represent neoplastic lesions.<\/jats:p>","DOI":"10.3390\/diagnostics15010101","type":"journal-article","created":{"date-parts":[[2025,1,3]],"date-time":"2025-01-03T10:17:23Z","timestamp":1735899443000},"page":"101","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Gastric Adenocarcinoma Incidentally Detected by PET\/CT with PSMA Ligands"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-8951-382X","authenticated-orcid":false,"given":"Cesare Michele","family":"Iacovitti","sequence":"first","affiliation":[{"name":"Division of Nuclear Medicine, Imaging Institute of Southern Switzerland, Ente Ospedaliero Cantonale, 6500 Bellinzona, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Barbara","family":"Muoio","sequence":"additional","affiliation":[{"name":"Division of Medical Oncology, Oncology Institute of Southern Switzerland, Ente Ospedaliero Cantonale, 6500 Bellinzona, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8214-562X","authenticated-orcid":false,"given":"Marco","family":"Cuzzocrea","sequence":"additional","affiliation":[{"name":"Division of Nuclear Medicine, Imaging Institute of Southern Switzerland, Ente Ospedaliero Cantonale, 6500 Bellinzona, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2864-5364","authenticated-orcid":false,"given":"Gaetano","family":"Paone","sequence":"additional","affiliation":[{"name":"Division of Nuclear Medicine, Imaging Institute of Southern Switzerland, Ente Ospedaliero Cantonale, 6500 Bellinzona, Switzerland"},{"name":"Faculty of Biomedical Sciences, Universit\u00e0 della Svizzera Italiana, 6900 Lugano, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9808-780X","authenticated-orcid":false,"given":"Giorgio","family":"Treglia","sequence":"additional","affiliation":[{"name":"Division of Nuclear Medicine, Imaging Institute of Southern Switzerland, Ente Ospedaliero Cantonale, 6500 Bellinzona, Switzerland"},{"name":"Faculty of Biomedical Sciences, Universit\u00e0 della Svizzera Italiana, 6900 Lugano, Switzerland"},{"name":"Faculty of Biology and Medicine, University of Lausanne, 1015 Lausanne, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"49","DOI":"10.1016\/j.eururo.2023.09.003","article-title":"European Association of Nuclear Medicine Focus 5: Consensus on Molecular Imaging and Theranostics in Prostate Cancer","volume":"85","author":"MacLennan","year":"2024","journal-title":"Eur.
