Abstract
The published Toumi et al's article is somewhat confusing to the readers. The cornual pregnancy (CP) defined as a pregnancy that occurs in a rudimentary horn of a uterus with a Müllerian anomaly according to William's textbook. The interstitial ectopic pregnancy (IEP) occurs in the interstitial part of the fallopian tube where it crosses the uterine muscular to enter the uterine cavity. The IEP sonographic findings include an empty uterus with an eccentrically placed gestational sac, located ≥1 cm from the endometrial margin and bordered by ≤ 5 mm myometrial rim.
