We are pleased that Dr. Abdelazim et al. are interested in our paper. We thank them for their valuable comments.
In some studies, the terms “interstitial” and “cornual” pregnancy are frequently used synonymously. Ackerman et al. in Radiology (1993) wrote, “interstitial (cornual) ectopic pregnancy represents 2%–3% of all ectopic pregnancy.” Faraj and Steel  in The Obstetrician and Gynaecologist (2007) wrote, “pregnancies implanted in this site are called interstitial (cornual) pregnancies.” Wright  in Journal of Diagnostic Medical Sonography (2008) wrote, “interstitial ectopic pregnancy, also referred to as a cornual ecopic pregnancy, is a rare form of ectopic pregnancy.” Similarly, Walid and Heaton  in German Medical Science (2010) wrote, “cornual (interstitial) ectopic pregnancy is an uncommon variant of ectopic pregnancy.”
In other studies, the two terms have been used for different types of ectopic pregnancy. Moawad et al. in the American Journal of Obstetrics and Gynecology (2010) wrote, “interstitial pregnancy sometimes is mistakenly referred to as cornual pregnancy and frequently confused with angular pregnancy.” Sargin et al. in Journal of Clinical and Diagnostic Research (2015) wrote, “interstitial and cornual ectopic pregnancy can be used in the place of each other. However, they actually describe two different entities.” Rizk et al. stated that the term “cornual ectopic pregnancy” should only be used in a rudimentary uterine horn, a unicornuate uterus, the cornual region of a septate uterus, a bicornuate uterus, or a uterus didelphys. The current version of William's Obstetrics supports the lemmas of Moawad et al., which describe cornual pregnancy as a conception that develops in the rudimentary horn of a uterus with a Müllerian anomaly.
Strickly by definition, our case should be described as interstitial pregnancy. We very much appreciate the suggestion from Dr. Abdelazim et al. and thank you once again for your time and interest.
