Most EPs implant in the fallopian tube and present in the first trimester; continuation beyond 10\u2009weeks is extremely uncommon.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case presentation:<\/jats:title>\n                    <jats:p>An 18-year-old primigravida at 12\u2009weeks\u2019 gestation presented with acute-onset lower abdominal pain, syncope, and 1\u2009week of dark-red spotting. She was hypotensive (BP 90\/60\u2009mmHg) and tachycardic (112\u2009bpm) with pale conjunctivae. Abdominal examination revealed lower-quadrant tenderness; pelvic exam showed a closed cervix and a tender posterior fornix. Transabdominal ultrasound demonstrated an empty uterus, a gestational sac with a fetal pole adjacent to the right adnexa, and moderate free intraperitoneal fluid.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Management and outcome:<\/jats:title>\n                    <jats:p>Emergency laparotomy was performed. Approximately 800\u2009mL of hemoperitoneum was evacuated. The right fallopian tube was found ruptured in the ampullary segment with extrusion of a formed fetus. Right salpingectomy was performed, and hemostasis achieved. The patient received 2\u2009units of packed red blood cells intraoperatively and recovered without complication. A follow-up ultrasound at 6\u2009weeks showed a normal remaining adnexa.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>This rare case of a 12-week tubal ectopic pregnancy with an advanced fetus highlights critical diagnostic challenges. Delayed presentation and lack of early prenatal imaging allowed the tubal pregnancy to progress to late gestation. High clinical suspicion and prompt ultrasound evaluation are essential for early detection of atypical ectopic pregnancies, to prevent catastrophic hemorrhage and preserve fertility.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/11795476251398664","type":"journal-article","created":{"date-parts":[[2025,11,29]],"date-time":"2025-11-29T14:01:16Z","timestamp":1764424876000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Advanced Tubal Ectopic Pregnancy Presenting with a Formed Fetus: Case Analysis and Review of Literature"],"prefix":"10.1177","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-0061-6458","authenticated-orcid":false,"given":"Chernet T.","family":"Mengistie","sequence":"first","affiliation":[{"name":"School of Medicine, College of Health Sciences, Addis Ababa University, Addis Ababa, Ethiopia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-9148-761X","authenticated-orcid":false,"given":"Mahiderekal M.","family":"Berkit","sequence":"additional","affiliation":[{"name":"School of Medicine, College of Health Sciences, Bule Hora University, Bule Hora, Ethiopia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Selam D.","family":"Temesgen","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, College of Health Sciences, Addis Ababa University, Addis Ababa, Ethiopia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-4647-111X","authenticated-orcid":false,"given":"Biruk T.","family":"Mengistie","sequence":"additional","affiliation":[{"name":"School of Medicine, College of Health Sciences, Addis Ababa University, Addis Ababa, Ethiopia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Solyana","family":"Bereded","sequence":"additional","affiliation":[{"name":"School of Medicine, College of Health Sciences, Addis Ababa University, Addis Ababa, Ethiopia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zebiba A.","family":"Degu","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, College of Health Sciences, Addis Ababa University, Addis Ababa, Ethiopia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,11,29]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41572-024-00579-x"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1038\/srep08487"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pgph.0004611"},{"issue":"2","key":"e_1_3_3_5_2","article-title":"ACOG practice bulletin no. 191: tubal ectopic pregnancy","volume":"131","author":"Committee on Practice Bulletins\u2014Gynecology","year":"2018","unstructured":"Committee on Practice Bulletins\u2014Gynecology.
