Abstract

Angular pregnancy is rare, in which the embryo in the lateral angle of uterine cavity and located medial to the utero-tubal junction. Angular pregnancy is differentiated from interstitial pregnancy. There is no report about term angular pregnancy in Republic of Korea, a few reports in other countries. Angular pregnancy has different clinical characteristics according to the trimester. We diagnosed angular pregnancy by ultrasonography and computed tomography (CT). The CT is a useful diagnostic method. We report a case of term angular pregnancy with placenta accreta and review the diagnostic process and complications.

Figure

• 

  Figure 1 Ultrasonographic finding at amenorrhea 7 weeks showed gestational sac located in right upper angular area.

• 

  Figure 2 Ultrasonographic finding after delivery is retained placenta and placenta accreta with suspicious corneal pregnancy.

• 

  Figure 3 (A) and (B) computed tomography scan showed lobulating enhancing mass-like lesion in right upper aspect of endometrial cavity (arrows). Overlying myometrium is less than 3 mm. Retained placenta is suggested on right cornual area. Remaining portion of uterus revealed mild enlargement with normal thickness of myometrium.

• 

  Figure 4 On the follow-up computed tomography scan after placental removal, myometrium on right cornual area is about 3.4 mm (arrows), indicating previous angular pregnancy. Hematoma is still noted within distended endometrial cavity.
