Intramural pregnancy is a rare type of ectopic pregnancy, which is diagnosed by transvaginal ultrasound and magnetic resonance imaging. Management strategies vary depending on the site of the pregnancy, the gestational age and the desire to maintain fertility. The incidence of intramural pregnancy in assisted reproductive technology is higher than that in natural pregnancy.
We present a case of intramural pregnancy after in vitro fertilization and elective single embryo transfer following salpingectomy. The patient was completely asymptomatic and her serum β-human chorionic gonadotropin level increased from 290 mIU/mL to 1759 mIU/mL. Three-dimensional transvaginal ultrasound indicated a heterogeneous echogenic mass arising from the uterine fundus which was surrounded by myometrium and a slender and extremely hypoechoic area stretching to the uterine cavity which was thought to be a fistulous tract. Therefore, we considered a diagnosis of intramural pregnancy and laparoscopic surgery was conducted at 7 wk gestation.
Early diagnosis and treatment of intramural pregnancy is significant for maintaining fertility.
Core Tip: We present a case of intramural pregnancy after in vitro fertilization and elective single embryo transfer following bilateral salpingectomy. The patient was diagnosed with intramural pregnancy by transvaginal ultrasound and then underwent laparoscopic surgery at 7 wk’ gestation. The patient recovered well at discharge and her serum β-hCG levels were negative after 4 wk.
