It is most commonly identified when investigating female infertility or in association with ruptured ectopic pregnancies. We experienced a rare and atypical presentation of SIN. A 33-year-old woman presented with a 1-hour history of acute lower abdominal pain associated with nausea and vomiting. CT and pelvic ultrasound revealed haemoperitoneum with no radiological evidence for its aetiology. Initial beta-human chorionic gonadotropin excluded ectopic pregnancy. A diagnostic laparoscopy was performed following clinical deterioration of the patient. Active bleeding of the right fallopian tube was identified and managed with a right partial salpingectomy, with subsequent histopathology revealing ruptured SIN. There have been no reported cases of SIN being a primary cause for an acute abdomen or haemoperitoneum in the absence of an ectopic pregnancy, making this case a surgical novelty.<\/jats:p>","DOI":"10.1136\/bcr-2020-237860","type":"journal-article","created":{"date-parts":[[2021,1,26]],"date-time":"2021-01-26T12:40:34Z","timestamp":1611664834000},"page":"e237860","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Ruptured salpingitis isthmica nodosa: a rare cause for spontaneous haemoperitoneum"],"prefix":"10.1136","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8534-4237","authenticated-orcid":false,"given":"Dora","family":"Huang","sequence":"first","affiliation":[{"name":"Department of Surgery, Austin Health, Heidelberg, Victoria, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sandon","family":"Lowe","sequence":"additional","affiliation":[{"name":"Department of Surgery, North West Regional Hospital, Burnie, Tasmania, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pravena","family":"Kumaran","sequence":"additional","affiliation":[{"name":"Department of Surgery, North West Regional Hospital, Burnie, Tasmania, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5763-5742","authenticated-orcid":false,"given":"Kay Tai","family":"Choy","sequence":"additional","affiliation":[{"name":"Department of Surgery, Austin Health, Heidelberg, Victoria, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,1,26]]},"reference":[{"key":"2025082623425899000_14.1.e237860.1","doi-asserted-by":"publisher","DOI":"10.1067\/j.cpradiol.2005.06.001"},{"key":"2025082623425899000_14.1.e237860.2","doi-asserted-by":"publisher","DOI":"10.1097\/00004347-198909000-00009"},{"key":"2025082623425899000_14.1.e237860.3","doi-asserted-by":"publisher","DOI":"10.1007\/s002619900502"},{"key":"2025082623425899000_14.1.e237860.4","doi-asserted-by":"publisher","DOI":"10.1148\/rg.271065042"},{"key":"2025082623425899000_14.1.e237860.5","doi-asserted-by":"crossref","first-page":"73","DOI":"10.1016\/j.ejogrb.2014.11.014","article-title":"An odyssey through salpingitis isthmica nodosa","volume":"184","author":"Bolaji","year":"2015","journal-title":"Eur J Obstet Gynecol Reprod Biol"},{"key":"2025082623425899000_14.1.e237860.6","doi-asserted-by":"crossref","first-page":"599","DOI":"10.1016\/S0015-0282(16)56207-4","article-title":"Salpingitis isthmica nodosa: a review of the literature, discussion of clinical significance, and consideration of patient management","volume":"60","author":"Jenkins","year":"1993","journal-title":"Fertil Steril"},{"key":"2025082623425899000_14.1.e237860.7","first-page":"333","article-title":"Diverticulosis and salpingitis isthmica nodosa (SIN) of the fallopian tube.
