“…Several cases reveal the phenomenon of transperitoneal gamete/embryo migration. [ 13 ] The absence of a tubal connection with the unicornuate uterus and the presence of a corpus luteum in the contralateral ovary may serve as evidence for it. It remains unknown whether chemotactic or other factors are involved in the transport of gametes or embryos across the peritoneal cavity to reach the contralateral and heterotopic tube.…”

Rationale: The incidence of a unicornuate uterus is 0.2% to 0.3% of the whole population. A unicornuate uterus is closely associated with obstetrical complications such as early miscarriages, ectopic pregnancy, and malpresentation. Patient concerns: A 32-year-old patient developed a rare ectopic pregnancy arising at a distal, fimbriated end of the undescended fallopian tube. Diagnoses: A transvaginal ultrasound scan revealed hemoperitoneum and no gestational sac in the uterine endometrium. A laparoscopic finding showed that high up in the right abdomen, just below the liver, an ectopic mass could be seen arising at a distal, fimbriated end of the fallopian tube, which was developed adjacent to the undescended right ectopic ovary. Interventions: After laparoscopic removal of the right salpinx, we removed it with a bag. Outcomes: One day after the operation, she was discharged without problems. Postoperative hysterosalpingography showed the unicornuate uterus with patent left and some right salpinx. Magnetic resonance imaging revealed a unicornuate uterus, right ovary at the right inferior hepatic area, a bilateral normal kidney, and double inferior vena cava. Lessons: This is the first reported case of its type. It demonstrated that ectopic pregnancy may occur in the upper abdomen, not in the pelvic cavity, in uterine anomaly, and double inferior vena cava; hence, we must thoroughly check the whole abdominal cavity. Additional imaging tests are needed after treatment to see if there are any abnormalities.

“…While uterine anomalies are the most frequent of the Müllerian ducts abnormalities, occurring in 2% to 4% of fertile women, structural abnormalities of the fallopian tubes and ovaries are exceedingly rare 6. While studies have reported rudimentary horn pregnancies, as well as tubal and cornual ectopic pregnancies occurring in both communicating and non-communicating horns,7 there is little published literature about ectopic pregnancies in the undescended ovary or tube in patients with an isolated unicornuate uterus.…”

Uterine anomalies are relatively uncommon and go undiagnosed in many cases. Ectopic pregnancies have been reported in such patients, although rarely, in the non-communicating rudimentary horns of unicornuate uteri. However, the case presented is of an ectopic pregnancy in the rudimentary fallopian tube related to an undescended ovary in a patient with an isolated unicornuate uterus, a phenomenon which is extremely rare.

“…Pregnancy in an undescended tube is a scarce type of ectopic pregnancy [1]. Only a few cases have been reported so far, posing a diagnostic challenge [2,3]. Our case constitutes transperitoneal gamete transportation evidence from the contralateral tube to the hypoplastic tube located outside of the pelvis [4].…”
