In this report, Callie, a 6-year-old spayed female German Shepherd, was presented to the Veterinary Teaching Hospital at the University of Bari for a specialist examination due to serosanguineous discharge from the vulva. All diagnostic tests recommended in the literature were performed to diagnose ORS. Notably, the Anti-M\u00fcllerian Hormone (AMH) assay, considered the gold standard for ORS diagnosis, was used, and the dog tested negative based on the established bibliographic cut-off values. However, advanced diagnostic techniques, including CT scans and laparoscopy, were performed, and histological examination ultimately confirmed the presence of ovarian tissue in the dog\u2019s abdominal cavity. This clinical case underscores the importance of combining hormonal tests with advanced imaging and surgical diagnostics to ensure accurate diagnosis. It highlights the limitations of relying solely on AMH values and emphasizes the need for further research into diagnostic tests, their cut-off values, and the role of collateral examinations to achieve definitive diagnoses in cases where hormonal assays yield inconclusive results.<\/jats:p>","DOI":"10.3390\/ani15030311","type":"journal-article","created":{"date-parts":[[2025,1,23]],"date-time":"2025-01-23T04:54:31Z","timestamp":1737608071000},"page":"311","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Unexpected Basal Anti-M\u00fcllerian Hormone Concentrations in a 6-Year-Old Bitch Presenting an Ovarian Remnant"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8203-4540","authenticated-orcid":false,"given":"Matteo","family":"Burgio","sequence":"first","affiliation":[{"name":"Department of Veterinary Medicine, University of Bari Aldo Moro, 70121 Bari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4994-768X","authenticated-orcid":false,"given":"Lluis","family":"Ferr\u00e9-Dolcet","sequence":"additional","affiliation":[{"name":"Independent Researcher, 08000 Barcelona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1287-478X","authenticated-orcid":false,"given":"Alice","family":"Carbonari","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine, University of Bari Aldo Moro, 70121 Bari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-9422-4746","authenticated-orcid":false,"given":"Lorenza","family":"Frattina","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine, University of Bari Aldo Moro, 70121 Bari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2688-0056","authenticated-orcid":false,"given":"Annalisa","family":"Rizzo","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine, University of Bari Aldo Moro, 70121 Bari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2792-8848","authenticated-orcid":false,"given":"Vincenzo","family":"Cicirelli","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine, University of Bari Aldo Moro, 70121 Bari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"501","DOI":"10.1016\/S0195-5616(91)50056-5","article-title":"The Ovarian Remnant Syndrome in the Bitch and Queen","volume":"21","author":"Wallace","year":"1991","journal-title":"Vet.
