Unicervical bicornuate uterus

ORPHA:180114Morphological anomaly

What it is

A rare non-syndromic uterine malformation characterized by a uterus with two uterine horns and only one cervix, resulting from a failure in the fusion of the two Müllerian structures. Depending on the degree of the fusion deficiency, the malformation may be complete with the cavities separated up to the internal orifice of the cervix and not linked, or partial when there is some linkage. Patients may present recurrent pregnancy loss or preterm labor.
