case_images: Serial monitoring of serum beta-hCG values are shown in Figure 1. The levels of beta-hCG had returned to below 50 U/L at the 3rd postoperative week (Figure 1).
case_images: The ultrasonograms before the surgery. (A) 2 gestational sacs with 2 yolk sacs at the left adnexa; (B) Both ovaries were normal; (C) No gestational sac in the uterine cavity and the endometrial thickness was 9.5mm. The presence of approximately 9 x 8mm hypoechoic nodules between the anterior uterine wall muscles suggests the possibility of uterine fibroids.

case_images: Transvaginal ultrasonography revealed no gestational sac in the uterine cavity but 2 gestational sacs with 2 yolk sacs at the left adnexa, the endometrial thickness was 9.5mm, and an unilateral twin ectopic pregnancy was diagnosed (Figure 2). The presence of approximately 9x8mm hypoechoic nodules between the anterior uterine wall muscles suggests the possibility of uterine fibroids (Figure 2).
case_images: Pathological result of curettage tissue. (A) The first pregnancy after magnification. (B) Histologic assessments confirmed the 2 distinct pregnancies at the same tube. The twins were dichorionic and diamniotic. (C) The second pregnancy after magnification.
