Introduction: The objective of this case report is to present the first known case of a primary omental ectopic pregnancy following frozen-thawed embryo transfer.
Case Report: A 35-year-old G0 female with severe male factor infertility underwent a frozen-thawed single embryo transfer. Serial transvaginal ultrasounds and beta human chorionic gonadotropin levels led to the diagnosis of ectopic pregnancy. The patient did not respond to medical management with methotrexate. On laparoscopy, an ectopic pregnancy was diagnosed on the greater omentum. The pregnancy was resected with the LigaSure device. Pathology evaluation was consistent with an omental ectopic pregnancy.
Conclusion: Although rare, omental ectopic pregnancy should remain in the differential in the setting of a pregnancy of unknown location.
Keywords: Frozen embryo transfer, In vitro fertilization, Omental ectopic pregnancy
