Giant cyst in heterotopic pregnancy: A case report

BACKGROUND: The coexistence of a heterotopic pregnancy with a giant ovarian cyst is an incredibly rare abnormal pregnancy in cases of natural conception. The incidence of this condition has increased significantly as a result of the continuous development of assisted reproductive technologies. When this type of pregnancy occurs, both the continuation of intrauterine pregnancy and the life of the pregnant woman are severely threatened. Early diagnosis and treatment using safe and effective methods are paramount in this situation. CASE SUMMARY: A 30-year-old primigravida at a gestation age determined as 8 wk 4 d by scan was admitted to the hospital with heterotopic pregnancy and a right ovarian cyst. Laparoscopic resection of the ectopic pregnancy was performed, but the intrauterine pregnancy and ovarian cyst were preserved. CONCLUSION: The approach to a patient with heterotopic pregnancy and a giant ovarian cyst is individualized base on the fertility requirements. We recommend the following: (1) If the patient satisfies parity and has no fertility requirement, a laparoscopic salpingectomy should be performed and the giant ovarian cyst and intrauterine pregnancy removed; (2) If the patient has fertility requirements wishes to have more children in the future, laparoscopic salpingectomy or salpingostomy should be performed and the intrauterine pregnancy preserved. Serial ovarian cyst aspiration can be performed under ultrasound and resection can be done after delivery; and (3) Heterotopic pregnancy should be diagnosed early by active surveillance during antenatal visits using ultra sound as this is important for the avoidance of catastrophic complications.
