Interstitial pregnancy is a form of ectopic pregnancy in an unusual location, implanting on the intramural part of the fallopian tube. Because the myometrium is highly distensible, it may allow an interstitial pregnancy to advance up to 16 weeks where it usually presents with rupture. Its late diagnosis and severe hemorrhagic complication accounts for a higher mortality rate compared to other ectopics. On the other hand, interstitial pregnancies that progress to term or near term are extremely rare. From the 10 cases published in literature reporting the delivery of a live term or near term fetus, only 1 of these cases has antenatally diagnosed the presence of interstitial pregnancy prior to rupture by investigating a probable placenta accreta found on ultrasound. This report discusses a case of a ruptured full term interstitial pregnancy diagnosed intraoperatively which resulted to a live mother and baby, and describes retrospectively the similar ultrasound findings of placenta accreta which was realized after rupture.
