title: Plicae palmatae of the cervical canals in uterus didelphys: MR imaging.
abstract: The plicae palmatae are normal endocervical folds on the anterior and posterior walls. The median longitudinal ridges of the plicae palmatae have been considered to represent a remnant of fused Müllerian ducts. We present a case of uterus didelphys in which the longitudinal ridge of the plicae palmatae were obviously demonstrated on both of the uterine cervices on axial T2-weighted image. The observation of the plicae palmatae on the duplicated uterine cervices indicates the plicae palmatae is an inherent structure of the cervical canal, not a remnant of fused Müllerian duct.
