case_images: Preoperative ultrasonographic image. EM: endometrium, GS: gestational sac. GS was distinct from EM at the left side of the uterus.

case_images: fig1
case_images: Transvaginal sonography revealed an ill-defined gestational sac and a fetal heart beat within the fundal myometrium, adjacent to the left cornua (Figure 1).
case_images: GS: gestation sac, TUBE: residual left fallopian tube. The GS was separate from residual left tube.

case_images: fig2
case_images: This cyst was distinct from the residual left fallopian tube (Figure 2).
case_images: GS: gestation sac. The uterus was cut with the harmonic scalpel, and the forceps were used to grasp the GS.

case_images: When the scalpel reached the gestational sac (Figure 3), serous fluid was released.
case_images: Histologic examination. Microscopic examination demonstrating villi within the myometrium and stroma.

case_images: Diffuse villi and decidual tissue were present within the uterine myometrium (Figure 4).
case_images: Perioperative serum beta-hCG levels. "Preop" is one day before surgery, and "POD6" is 6 days post surgery, "POD14" is 14 days post surgery. The beta-hCG dropped rapidly postoperatively.

case_images: The patient's postoperative course was uneventful, and the hCG level decreased appropriately (Figure 5).
case_images: Postoperative HSG (hysterosalpingography). No filling defect is evident. Therefore the excised portion of the uterus containing the pregnancy was not one horn of a bicornuate uterus.

case_images: fig6
case_images: Followup hysterosalpingography (HSG) three months postoperatively showed no change in the appearance of the uterus (Figure 6) as compared with an HSG obtained prior to the pregnancy.
case_images: HSG prior to the pregnancy. The left tube was transected at the site of a previous ectopic pregnancy (left tubal pregnancy).

case_images: Additionally, the absence of a filling defect confirmed that the tissue removed was not a horn of a bicornuate uterus (Figure 7).
