• A bicornuate uterus is a type of uterine malformation, but in some mammals, including rodents and pigs, it is normal
• A bicornuate uterus is formed during embryogenesis. The fusion process of the upper part of the paramesonephric ducts is altered. As a result, the lower part of the uterus is unitary while the upper part is bifurcated

• It is possible to Dx a bicornuate uterus using gynecologic ultrasonography, specifically sonohysterography and MRI
• However, as there is no indication to do such procedures on asymptomatic women, the presence of a bicornuate uterus may not be detected until pregnancy or delivery
• In a C section (usually done due to malpresentation), the irregular shape of the uterus will be apparent
• Other less reliable Dx imaging methods include hysterosalpingography and hysteroscopy; these procedures are typically done during the course of an infertility Ix
