On the look out for a rarity--interstitial/cornual pregnancy.

Interstitial (cornual) pregnancy is a rare form of ectopic pregnancy that can be difficult to diagnose both clinically and ultrasonographically. However, early detection is essential to avoid fatal outcome. We report a case of interstitial/cornual ectopic pregnancy. The patient presented with uterine rupture over the cornual region resulting in catastrophic bleeding. The risk factors, clinical features and ultrasonographic signs are reviewed.
