This is a case report describing an ectopic pregnancy occurring in the remnant stump following salpingectomy. A pregnancy implanted in this location appears very uncommon, thereby rendering the correct diagnosis challenging. This contribution comprises a case description, a presentation of the different diagnostic and therapeutic methods available to date, as well as a succinct literature review. We have also highlighted the requirement of performing salpingectomy by sectioning the isthmus of the uterine tube at the uterine horn, then coagulating the horn's intramural portion. Lastly, we have taken into consideration a series of practical recommendations.
What is already known about the topic?
1. While interstitial ectopic pregnancies appear to be very rare, they are associated with a higher mortality than those with ampulary locations.
2. The differential diagnosis of an intrauterine pregnancy may prove difficult.
3. There are two treatment options in the event of ectopic pregnancies, with the surgical approach more indicated for these rare ectopic locations.
What does this article bring up for us?
1. Do not rely on endocavitary imaging at the early pregnancy stage, as they may concern pseudo-bags.
2. The requirement of performing salpingectomy by sectioning the isthmus of the uterine tube at the uterine horn, thereby preventing residual stumps able to host cornual pregnancy.
3. Cornual pregnancies may recur following drug treatment.
