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

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.
