Ultrasound is the primary diagnostic tool to locate pregnancy outside the uterus and identify complications such as haemoperitoneum. In inconclusive cases, MRI is an adjunctive imaging modality offering more precise tissue differentiation and helpful to location identification. Presented is an unusual case of tubal pregnancy. The patient in her 30s, who was 14 weeks into her first pregnancy, had a suspected abdominal pregnancy. Both transabdominal ultrasound and an MRI indicated an ectopic pregnancy, likely originating from the right fallopian tube. A successful laparotomy and right salpingectomy were performed without complications. Rarely, as in this case, large unruptured and advanced tubal pregnancies can mimic an abdominal pregnancy, underscoring the importance of disease recognition and familiarity with uncommon image findings. An accurate diagnosis of pregnancy location is crucial for effective case management.<\/jats:p>","DOI":"10.1136\/bcr-2023-256090","type":"journal-article","created":{"date-parts":[[2023,10,10]],"date-time":"2023-10-10T12:46:20Z","timestamp":1696941980000},"page":"e256090","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Large unruptured tubal pregnancy mimicking abdominal pregnancy"],"prefix":"10.1136","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0980-2128","authenticated-orcid":false,"given":"Kuntharee","family":"Traisrisilp","sequence":"first","affiliation":[{"name":"Obstetric and Gynecology, Chiang Mai University, Faculty of Medicine, Chiang Mai, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sethawat","family":"Sethasathien","sequence":"additional","affiliation":[{"name":"Obstetric and Gynecology, Chiang Mai University, Faculty of Medicine, Chiang Mai, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2023,10,10]]},"reference":[{"key":"2025082623143564000_16.10.e256090.1","doi-asserted-by":"crossref","first-page":"213","DOI":"10.1007\/s10995-019-02842-0","article-title":"Trends in ectopic pregnancy diagnoses in United States emergency departments, 2006-2013","volume":"24","author":"Mann","year":"2020","journal-title":"Matern Child Health J"},{"key":"2025082623143564000_16.10.e256090.2","doi-asserted-by":"publisher","DOI":"10.1148\/rg.286085506"},{"key":"2025082623143564000_16.10.e256090.3","doi-asserted-by":"crossref","first-page":"e91","DOI":"10.1097\/AOG.0000000000002560","article-title":"ACOG practice bulletin No.193: Tubal ectopic pregnancy","volume":"131","year":"2018","journal-title":"Obstet Gynecol"},{"key":"2025082623143564000_16.10.e256090.4","doi-asserted-by":"crossref","first-page":"1104","DOI":"10.1007\/s00261-020-02681-6","article-title":"The many faces of ectopic pregnancies: Demystifying the common and less common entities","volume":"46","author":"Ucisik-Keser","year":"2021","journal-title":"Abdom Radiol (NY)"},{"key":"2025082623143564000_16.10.e256090.5","doi-asserted-by":"publisher","DOI":"10.1097\/OGX.0b013e31829cdbeb"},{"key":"2025082623143564000_16.10.e256090.6","doi-asserted-by":"publisher","DOI":"10.1093\/humrep\/17.12.3224"},{"key":"2025082623143564000_16.10.e256090.7","doi-asserted-by":"crossref","first-page":"1043","DOI":"10.2214\/ajr.147.5.1043","article-title":"Sonographic findings in abdominal pregnancy","volume":"147","author":"Stanley","year":"1986","journal-title":"American Journal of Roentgenology"},{"key":"2025082623143564000_16.10.e256090.8","doi-asserted-by":"publisher","DOI":"10.1159\/000342997"},{"key":"2025082623143564000_16.10.e256090.9","doi-asserted-by":"crossref","first-page":"904","DOI":"10.2214\/AJR.13.10644","article-title":"Beyond ultrasound: CT and MRI of ectopic pregnancy","volume":"202","author":"Kao","year":"2014","journal-title":"AJR Am J Roentgenol"},{"key":"2025082623143564000_16.10.e256090.10","doi-asserted-by":"publisher","DOI":"10.1148\/rg.325115153"},{"key":"2025082623143564000_16.10.e256090.11","doi-asserted-by":"crossref","first-page":"161","DOI":"10.1007\/s10140-021-01974-7","article-title":"Ectopic pregnancy: a resident\u2019s guide to imaging findings and diagnostic pitfalls","volume":"29","author":"Houser","year":"2022","journal-title":"Emerg Radiol"},{"key":"2025082623143564000_16.10.e256090.12","doi-asserted-by":"crossref","first-page":"462","DOI":"10.5468\/ogs.2017.60.5.462","article-title":"Preoperative diagnostic clues to ovarian pregnancy: retrospective chart review of women with ovarian and Tubal pregnancy","volume":"60","author":"Seo","year":"2017","journal-title":"Obstet Gynecol Sci"},{"key":"2025082623143564000_16.10.e256090.13","doi-asserted-by":"publisher","DOI":"10.1097\/01.AOG.0000148271.27446.30"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2023-256090","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T06:14:46Z","timestamp":1756275286000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2023-256090"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,10]]},"references-count":13,"journal-issue":{"issue":"10","published-online":{"date-parts":[[2023,10,10]]},"published-print":{"date-parts":[[2023,10]]}},"alternative-id":["10.1136\/bcr-2023-256090"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2023-256090","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2023,10]]}}}
