Two Cases of Ectopic Pregnancy Mimicking Gestational Trophoblastic Disease

Figure 1

MR image performed at 7 weeks and 5 days in case 1 shows an interstitial pregnancy. A heterogeneously-enhanced hypervascular mass is identified on the right side of the uterine fundus. The mass measures 52 mm, which is larger than a GS at the corresponding estimated gestational age. Arrows indicate the pregnancy-associated lesion. (a) A sagittal T2-weighted MR image. (b) An axial T2-weighted MR image. (c) An enhanced axial MR image. (d) Gross pathology of the uterus and the pregnancy-related tissue. (e) An enlarged view of the implantation site.
