title: Diagnosis of combined intra and extra uterine gestations.
abstract: The ultrasound diagnosis of an ectopic pregnancy can be extremely difficult to achieve even for an experienced operator. The two case studies show that however rare any phenomenon might be, this should not be a reason for excluding it as a possible diagnosis. I hope that this article will help sonographers in the future to be aware of the possible existence of a combined intra and extra uterine pregnancy.
