Communicating bicornuate uterus with double cervix and septate vagina: An uncommon malformation diagnosed with MR imaging

We report a case of communicating uterus diagnosed with MRI. These uterine malformations are characterized by a communicating tract between two separate uterocervical cavities, which is usually detected with hysterosalpingography performed for a suspected uterine malformation. In our patient MRI was performed after the clinical finding of a double cervix and a vaginal septum and demonstrated two separate uterine cavities, each of them with its own junctional area, and an isthmian transverse communicating tract with endometrial tissue inside, which helped make the diagnosis of a type-4a communicating uterus according to Toaff.
