Despite 10\u00a0weeks of amenorrhea and a serum \u03b2-human chorionic gonadotropin (\u03b2-HCG) level\u2009&amp;gt;10\u2009000\u00a0U\/l, several ultrasound (US) scans in another facility failed to detect intrauterine pregnancy. Her history includes past motor vehicle accident. During emergency laparotomy, a moderate amount of hemoperitoneum was seen with a normal uterus and adnexa. A right-sided pelvic wall hematoma was noted. Abdominal US and computed tomography scans demonstrated a large retroperitoneal hematoma with active bleeding. The hematoma spanned from the liver to the pelvic brim with a central cyst-like structure that resembled a gestational sac. During an upper midline laparotomy performed by a multidisciplinary team, the hematoma was evacuated. Histopathological examination of structures within the clot identified chorionic villi. The patient underwent blood transfusions and recovered uneventfully under proper antibiotic prophylaxis. \u03b2-HCG levels dropped to zero within 2 weeks.<\/jats:p>","DOI":"10.1093\/jscr\/rjaf413","type":"journal-article","created":{"date-parts":[[2025,5,31]],"date-time":"2025-05-31T07:42:55Z","timestamp":1748677375000},"source":"Crossref","is-referenced-by-count":2,"title":["A rare case of a retroperitoneal pregnancy: case report"],"prefix":"10.1093","volume":"2026","author":[{"given":"Manol","family":"Sokolov","sequence":"first","affiliation":[{"name":"Department of Surgery, UMHAT \u201cAlexandrovska\u201d, Medical University Sofia , \u201cSt. Georgi Sofiiski\u201d 1 Str., Sofia 1431 ,","place":["Bulgaria"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Magdalena","family":"Belyanova","sequence":"additional","affiliation":[{"name":"Department of Radiology, UMHAT \u201cAlexandrovska\u201d, Medical University Sofia , \u201cSt. Georgi Sofiiski\u201d 1 Str., Sofia 1431 ,","place":["Bulgaria"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julia","family":"Dimova","sequence":"additional","affiliation":[{"name":"Department of Radiology, UMHAT \u201cAlexandrovska\u201d, Medical University Sofia , \u201cSt. Georgi Sofiiski\u201d 1 Str., Sofia 1431 ,","place":["Bulgaria"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin","family":"Krupev","sequence":"additional","affiliation":[{"name":"Department of Radiology, UMHAT \u201cAlexandrovska\u201d, Medical University Sofia , \u201cSt. Georgi Sofiiski\u201d 1 Str., Sofia 1431 ,","place":["Bulgaria"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rumen","family":"Dimitrov","sequence":"additional","affiliation":[{"name":"Second Gynecological Clinic -
