There is a higher incidence with assisted reproduction techniques (ART) and radiology can be pivotal in its diagnosis. A 28-year-old woman underwent ART and at 7 weeks\u2019 gestation presented with acute right iliac fossa pain. Transvaginal ultrasound (US) imaging confirmed a viable intrauterine pregnancy. The patients\u2019 pain persisted however, and transabdominal US demonstrated a complex, heterogeneous right adnexal mass. Subsequent magnetic resonance imaging (MRI) confirmed an HP with a ruptured ectopic and haemoperitoneum. Emergency laparoscopic surgery and right salpingo-oopherectomy were performed without complication. We highlight the importance of considering HP as a diagnosis in the acute gravid abdomen, especially when initial investigations have confirmed a viable intrauterine pregnancy. Furthermore, this case highlights MRI as a useful modality in complex cases due to its high soft tissue contrast resolution using non-ionising radiation.<\/jats:p>","DOI":"10.1136\/bcr-2020-239178","type":"journal-article","created":{"date-parts":[[2020,12,23]],"date-time":"2020-12-23T16:46:34Z","timestamp":1608741994000},"page":"e239178","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":6,"title":["Acute
