Sonographic Diagnosis of Interstitial (Cornual) Ectopic Pregnancy: A Case Report

Interstitial or cornual pregnancy is an uncommon form of ectopic pregnancy that can be difficult to diagnose both clinically and sonographically. Although infrequent, interstitial ectopic pregnancy carries a greater mortality risk than common forms of tubal ectopic pregnancy. The authors present a case of an interstitial ectopic pregnancy diagnosed sonographically, and they review the associated literature.
