This case report details the challenges in identifying and managing an exceptionally rare case of abdominal pregnancy without assisted reproduction. The patient's initial misdiagnosis underscores the complexities in diagnosis, emphasizing the importance of comprehensive imaging techniques.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case presentation:<\/jats:title>\n                    <jats:p>We present the case of a 36-year-old gravida 5, para 3, with a history of dilation and curettage, experiencing a heterotopic pregnancy involving delayed miscarriage in both uterine and abdominal cavities. Despite presenting symptoms of pelvic pain and abnormal vaginal bleeding, the abdominal pregnancy was initially overlooked in ultrasound examinations. The accurate diagnosis was only achieved post-miscarriage, leading to a timely intervention through laparotomy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Clinical discussion:<\/jats:title>\n                    <jats:p>The absence of identifiable risk factors, except for the patient's history of dilation and curettage, highlights the spontaneous nature of this non-assisted reproduction-related pregnancy. This case emphasizes the challenges in diagnosing and managing spontaneous heterotopic pregnancies, particularly when an abdominal pregnancy is involved. Vigilance and advanced imaging techniques are crucial for early recognition and appropriate intervention.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>This unique case underscores the difficulties in diagnosing and managing spontaneous heterotopic pregnancies, especially when an abdominal pregnancy is present. Vigilance and advanced imaging are essential to identify rare occurrences like abdominal pregnancies that may go unnoticed in conventional ultrasound examinations. Early recognition and intervention are critical in averting potential life-threatening consequences associated with this uncommon condition.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Highlights<\/jats:title>\n                  <\/jats:sec>","DOI":"10.1016\/j.ijscr.2024.109498","type":"journal-article","created":{"date-parts":[[2024,3,11]],"date-time":"2024-03-11T02:59:47Z","timestamp":1710125987000},"update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":2,"title":["Early abdominal pregnancy in a spontaneous heterotopic pregnancy: Case report"],"prefix":"10.1097","volume":"117","author":[{"given":"Marzouk","family":"Khouloud","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Othman","family":"Maroua","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hafsi","family":"Montacer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Swileh","family":"Salma","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Smida","family":"Safa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bouchahda","family":"Haifa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-41-20260423","first-page":"333","article-title":"Abdominal pregnancy in the United States: frequency and maternal mortality","volume":"69","author":"Atrash,","year":"1987","journal-title":"Obstet.
