Ovarian Teratoma With Concurrent Ectopic Pregnancy at Diagnostic Laparoscopy [4

Abstract

BACKGROUND: Benign mature cystic teratomas account for approximately 33% of all benign ovarian neoplasms, with the majority occurring between the ages of 10 and 30 years. Studies have shown that approximately 60% are asymptomatic at diagnosis, and approximately 10% of cases are found during pregnancy. However, there have been few documented cases of a concurrent ectopic pregnancy with an ovarian teratoma. CASE: A 24-year-old multiparous woman presented with persistent pelvic pressure and pain over the course of a month. She had a plateauing β-hCG level without evidence of an intrauterine pregnancy. She underwent diagnostic laparoscopy, with findings of a ruptured right ectopic pregnancy and bilateral ovarian masses. The left ovarian mass measured 6 cm; as a result, both a right salpingo-oophorectomy and a left ovarian cystectomy were performed. Pathology confirmed a ruptured right ectopic pregnancy and bilateral benign mature cystic teratomas. CONCLUSION: The presence of enlarged ovarian teratomas can predispose patients to many complications such as ovarian torsion. Therefore, it may be beneficial to perform interventions such as an ovarian cystectomy at the time of surgery for other pathologies such as a ruptured ectopic pregnancy.
