Twin pregnancy in a partial septate uterus and the contribution of Magnetic Resonance Imaging (MRI). A case report

Introduction: Septate uterus is the most common (34%-48%) structural abnormality of all Müllerian duct defects. It results from incomplete resorption of the medial septum after the complete fusion of the müllerian ducts has occurred and is associated with infertility and obstetrical complications. Magnetic Resonance Imaging (MRI) is used for diagnosing müllerian malformations with a specificity of 96 to 100%. Case report: We present the rare case of a viable twin pregnancy in a partial septate uterus and discuss the role of Magnetic Resonance Imaging (MRI) in congenital uterine malformations. The diagnosis of uterine malformation was made before pregnancy. The viability of the twin gestation in a primiparous young woman was confirmed by transabdominal and transvaginal sonography. The location of the foetuses was confirmed by Magnetic Resonance Imaging (MRI). A specific schedule of prenatal screening was provided. Two healthy neonates were delivered by caesarean section in the 34 th week of gestation. Discussion: In this case report a very rare high risk pregnancy and its successful outcome are described. The importance of Magnetic Resonance Imaging (MRI) in the management of this high risk pregnancy is also highlighted.
