Ultrasound is widely used for diagnosis of ectopic pregnancies, and is the accepted imaging modality to rule out ectopic pregnancies. Rudimentary horn pregnancy can be difficult to differentiate from an abdominal pregnancy. The visualization of an intact placenta with welldefined borders seems to be a key in the differential diagnosis. It is also helpful to obtain confirmation of a diagnosis such as this with another imaging modality. Magnetic resonance imaging (MRI) is the most helpful and widely recognized imaging modality for this purpose.
