Intrauterine hydatidiform mole complicated with tubal ectopic pregnancy: a case report

Heterotopic pregnancies are rare pathological pregnancy disorders in clinical practice. However, the number of cases has increased with the widespread use of ovulation induction drugs in recent years. The clinical manifestations of heterotrophic pregnancies are diverse and easy to missed or misdiagnosed. A 33-year-old married Gravida1 Para 0 + 0 patient was admitted on December 8, 2020 with intermittent abdominal pain 18 days after uterine curettage for complete hydatidiform mole of 8 weeks gestation. She had ovulation-promoting drugs prior to the index pregnancy. Hysteroscopic-directed endometrial biopsy and laparoscopic left tubal surgery were offered to her; and she is being followed up with serial pelvic ultrasounds and β-Human Chorionic Gonadotrophin (βHCG) assays. This case study presents a case of intrauterine hydatidiform mole complicated with tubal pregnancy to highlight the problems associated with its diagnosis and treatment.
