Variations in clinical presentation of unicornuate uterus with non-communicating rudimentary horn (class IIB of the American Fertility Society classification)

Abstract

Objective: The unicornuate uterus is a rare uterine malformation (2.4–13.7% of all uterine malformations (Engmann et al., 2004)) which usually features a rudimentary accessory horn in more than 75% of the cases. Pregnancy in the rudimentary horn is rare, but the complications attached to such pregnancies could be defined as the first clinical manifestation of rudimentary horn. Case Reports: We hereby describe five cases of unicornuate uterus with rudimentary horn (UUWRH), each one with a different clinical presentation and without any correct preoperative diagnosis, and henceforth reflect on the practical aspects learnt about the differential diagnosis and management of this rare malformation. Conclusion: Our experience with UUWRH is that perhaps asymptomatic cases are not as rare as reported in medical literature. We highlight the need for a greater awareness of the differential diagnosis of genital malformations and accurate in the exact subtype and their correct treatment.
