Tubo-Omental Ectopic Pregnancy

Abstract

A 26-year-old woman, gravida 1, para 0, consulted our department because of lower abdominal pain for days. She had undergone intrauterine insemination at a local clinic. The serum quantitative human chorionic gonadotropin (hCG) level 5 weeks after intrauterine insemination was 2096 mIU/mL. Transvaginal ultrasound revealed no evidence of intrauterine pregnancy, but an extra-adnexal heterogeneous 2.5 cm × 2.1 cm mass was adjacent to the right ovary (Fig. 1), suggesting ectopic pregnancy. The patient preferred medical treatment with methotrexate 50 mg/m2 intramuscularly.
