Intramural Pregnancy Implanted Into a Myometrial Defect Caused by Curettage: Diagnosis With Transvaginal Sonography and Preconception and Postconception Magnetic Resonance Imaging

摘要

A 31-year-old woman, gravida 0, para 0, was referred to ourhospital for suspected ectopic pregnancy at 7 weeks’ gestation. She had undergone conization of the uterine cervix foradenocarcinoma in situ 2 years previously. Transvaginalsonography revealed a gestational sac with a live fetus at thefundus of the uterus (Figure 1A), and color Doppler sonography showed marked hypervascularity around the gestational sac, which was located within the fundic uterine wall.Because this sonographic appearance strongly suggestedintramural pregnancy at the fundic uterine wall, we askedthe patient whether she had previously undergone surgeryof the uterine corpus. She then told us that an artificial abortion had been performed by dilation and curettage for socialreasons 10 years previously (gravida 1).
