Background: Unilateral twin tubal ectopic pregnancy is an extremely rare form of ectopic pregnancy with an estimated incidence of 1 in 125,000 spontaneous pregnancies. Case presentation: A 31-year-old woman (G2P1) with secondary infertility of three years presented with right-sided pelvic pain and six weeks of amenorrhoea following simple ovarian stimulation. Pelvic ultrasound revealed an empty uterine cavity and a right adnexal mass containing two distinct gestational sacs (Figure 1 and Figure 2). Serum β-hCG was 9,200 mIU/mL. Laparotomy confirmed a right unilateral twin tubal ectopic pregnancy (Figure 3), and a right salpingectomy was performed. Histopathology confirmed two separate gestational sacs with chorionic villi. Postoperative recovery was uneventful, and the patient subsequently achieved a full-term intrauterine pregnancy. Conclusion: Unilateral twin tubal ectopic pregnancy remains a diagnostic and therapeutic challenge. Early ultrasound suspicion, prompt surgical intervention, and preservation of contralateral tubal function are critical for future fertility.
