ABSTRACT

This case report shows the successful use of early medical treatment in an intramural ectopic pregnancy which occurred after ovulation induction and artificial intrauterine insemination (IUI). In the 5th week of the IUI, transvaginal ultrasound revealed an asymmetrically enlarged uterus and a gestational sac within the myometrium. The diagnosis of intramural pregnancy was confirmed by MRI. The delineation of a gestational sac within the myometrium can be best achieved by MR imaging which also obviates the hazardous effects of X-ray imaging. After methotreaxate treatment, the blood -hCG concentration decreased gradually. Early diagnosis and treatment are crucial to prevent the massive bleeding resulting from the rupture of the distended sac.
