Case Discussion

From the Radiopaedia uterine didelphys article:

A uterus didelphys is a type of Müllerian duct anomaly (class III) where there is complete duplication of uterine horns as well as duplication of the cervix, with no communication between them.  

It results from failed ductal fusion that occurs between the 12th and 16th week of pregnancy and is characterized by two symmetric, widely divergent uterine horns and two cervixes. The uterine volume in each duplicated segment is reduced. As with most uterine anatomical anomalies, there is an increased incidence of fertility issues, and Müllarian abnormalities in general are over represented in infertile women. The chance of seeing a pregnancy to term is significantly reduced, down to only 20%, with a third of pregnancies ending in abortion and over half in premature deliveries. Only 40% of pregnancies resulted in living children
