A case of excision of ovarian torsion necrosis due to luteoma in a female who conceived a twin pregnancy through in vitro fertilization misdiagnosed with acute appendicitis.

The aim of this study was to describe a case of ovarian torsion necrosis due to delayed treatment of luteoma in a woman with IVF twin pregnancy who was misdiagnosed with acute appendicitis. We summarized the clinical manifestations and diagnosis of luteoma in a woman with IVF twin pregnancy and reviewed the relevant literature. We report the case of a 34-year-old Asian female who became pregnant through in vitro fertilization (IVF) and had acute right underbelly pain at 26 weeks and 6 days of gestation, which was misdiagnosed as acute appendicitis. Written consent was obtained from the patient. After fasting for a short duration and receiving anti-inflammatory and intravenous fluid replacement treatment after admission, the woman experienced increased right lower abdominal pain without relief and decreased fetal movement. B-ultrasound and CT examination showed that luteoma torsion was possible, and we performed emergency surgical laparotomy. During the operation, it was found that the right ovary was enlarged, the fallopian tube was twisted 720 degrees, and there was no lesion in the appendix. The right necrotic ovary was removed, and pathological results showed a hemorrhagic corpus luteum in the right ovary. The patient's abdominal pain was relieved after the operation and the pregnancy was continued. This is a typical case of ovariectomy associated with a luteoma of pregnancy. Whether in vitro fertilization and related procedures increase the risk of luteoma and whether they increase the risk of ovarian torsion necrosis in the case of luteoma formation are questions that need further study.
