Congenital Müllerian Anomalies
Müllerian duct anomalies are congenital abnormalities that occur when the Müllerian ducts (paramesonephric ducts) do not develop correctly. This may be as a result of complete agenesis, defective vertical or lateral fusion, or resorption failure.
The arcuate uterus is a form of a uterine anomaly or variation where the uterine cavity displays a concave contour towards the fundus.
Uterine didelphys is complete uterine nonfusion with 2 uteri and 2 cervices separated by a normal myometrium. In a bicornuate uterus, a normal muscular septum can extend to the internal os (partial or bicornuate unicollis) or close to the external os (complete or bicornuate bicollis).
