Bicornuate uterus accounts for approximately 10% of all congenital uterine anomalies.

The importance of identifying and distinguishing from a septate uterus is important as far as management modality and prognosis is concerned.

Criteria for bicornuate uterus include

• intercornual angle >75-105 degrees
• intercornual distance >4 cm
• fundal depression depth >1 cm

MR is nearly 100% accurate.
