Abstract and Introduction


Introduction: We report that the coincidence of ovarian tumor and pregnancy poses significant challenges that are more pronounced if the pregnancy is ectopic.

Case presentation: Here, we report a rare and interesting case of a 24-year-old nulliparous Spanish woman who experienced the coincidental occurrence of left tubal pregnancy and dysgerminoma in the right ovary. The corpus luteum settled in the right ovary. A right adnexectomy and left linear salpingostomy were performed. Remarkably, our patient became pregnant spontaneously after surgery. The pregnancy occurred prior to starting chemotherapy, and the intra-uterine pregnancy was carried to term; later, she also had another normal pregnancy. Our patient has done well without chemotherapy.

Conclusions: Our report on the challenges of diagnosis and treatment faced in this case can help clinicians better understand and manage these pathologies. We have not found any similar cases in the literature.


The coincidence of an ovarian tumor and a pregnancy poses significant challenges for differential diagnosis, which are more pronounced if the pregnancy is ectopic. In cases of ectopic pregnancy, a positive human β-chorionic gonadotropin (β-hCG) test result, absence of a visible intra-uterine gestation upon ultrasound examination and presence of an ovarian tumor also suggest a germ cell tumor. We present the exceptional case of a patient who experienced the coincidental occurrence of a tubal ectopic pregnancy with a large tumor in the contralateral ovary that was revealed to be a dysgerminoma. Interestingly, our patient became pregnant after undergoing laparotomy for a right adnexectomy and a left linear salpingostomy. Our patient carried this pregnancy to term and later had another normal intra-uterine pregnancy that was also carried to term.
