A 22-year-old woman was initially misdiagnosed with a ruptured corpus luteum and treated with analgesics at a local clinic. Persistent symptoms led her to our hospital, where a pelvic ultrasound revealed a 5.2 cm \u00d74.8 cm hematoma. Despite the significant hematoma, her vital signs were stable. A urine pregnancy test was positive, \u03b2-hCG was 5553 mIU\/mL, and hemoglobin (Hb) was 6.3 g\/dL. After a blood transfusion, methotrexate (MTX) was administered, reducing \u03b2-hCG to 4428 mIU\/mL by day 5. Four weeks later, \u03b2-hCG was 723.6 mIU\/mL, and a second MTX dose was given. Three weeks later, \u03b2-hCG was 4.7 mIU\/mL, and Hb was 12.4 g\/dL. In conclusion, a \u201cwait-and-see\u201d approach with serial hCG testing and repeated ultrasounds is recommended in unclear cases.<\/jats:p>","DOI":"10.4103\/gmit.gmit-d-24-00006","type":"journal-article","created":{"date-parts":[[2025,5,22]],"date-time":"2025-05-22T01:00:17Z","timestamp":1747875617000},"page":"189-192","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":3,"title":["Ruptured
