Med."],"abstract":"<jats:p>Primary omental pregnancy is an extremely rare form of ectopic pregnancy. We report a case of successful laparoscopic management in a 19-year-old nulliparous woman with no traditional risk factors. Despite sonographic evaluation, including transvaginal, transabdominal, and multi-organ abdominal ultrasonography, the ectopic lesion was not identified preoperatively. Diagnostic laparoscopy was performed, but initial pelvic exploration was also negative. Only after lifting the bowel was a 2\u2005cm omental pregnancy discovered, concealed beneath the bowel, and completely excised. Postoperatively, serum beta-human chorionic gonadotropin (\u03b2-hCG) declined by 70.3% on day 1 and 95.3% on day 4 without methotrexate use. This case underscores two points: first, systematic laparoscopic exploration beyond the pelvis is essential when initial inspection is negative; second, the absence of traditional risk factors does not exclude rare-site ectopic implantation.<\/jats:p>","DOI":"10.3389\/fmed.2026.1938779","type":"journal-article","created":{"date-parts":[[2026,10,7]],"date-time":"2026-10-07T05:53:07Z","timestamp":1791352387000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Case
