Interstitial ectopic pregnancy


This case is a typical demonstration of an interstitial ectopic pregnancy, with a thin surrounding myometrial layer (myometrial mantle) and hyperechoic line from the mass to the endometrium (interstitial line sign).

The patient in this case was not on the oral contraceptive pill and had a bHCG of 1300. She was treated with IM methotrexate and serial bHCG follow up.
