Ectopic pregnancy is a major cause of 1st trimester pregnancy deaths. It occurs in various locations in the abdominopelvic cavity. Ultrasonography is a first-line, rapid, and noninvasive modality for ectopic pregnancy evaluation. MRI can help clarify equivocal cases.

Here, we will review the imaging findings and mimickers of ectopic pregnancies.
