Magnetic resonance imaging of tubal ectopic pregnancy: correlation with intraoperative findings

Ectopic pregnancy is defined as a pregnancy that occurs outside of the uterine cavity (ACOG Committee on Practice Bulletins, 2018 [1]). Ectopic pregnancy is occasionally diagnosed with MRI. Particularly, when ultrasound is nondiagnostic, it is essential that radiologists are able to recognize findings of ectopic pregnancy on MRI in the emergent setting. This novel case report demonstrates specific MR imaging signs recently proposed in the literature to help identify a tubal gestational sac, the most common type of ectopic pregnancy, and is the first reported case demonstrating intraoperative correlation with MRI findings of tubal ectopic pregnancy.
