RESUMO
Objective To observe imaging features of uterus duplication combined with mesonephric duct dysplasia related abnormalities.Methods Imaging data of 17 female with uterus duplication and renal dysplasia were retrospectively analyzed.Seven patients underwent CT and 10 patients underwent MR scanning.Results The basic abnormalities in 17 patients were uterus duplication combined with unilateral renal-ureter dysplasia with/without other associated malformation which were further classified as follows:①7 patients presented as basic abnormalities without other associated malformations,include 5 (CT diagnosed 1,MR diagnosed 4) with uterus duplex and unilateral renal-ureter agenesis,2 (CT 1,MR 1) with uterus bifidus and unilateral renal-ureter dysplasia;②2 patients (CT 1,MR 1) presented as basic abnormalities accompanied with ectopic ureter orifice,uterus duplex and unilateral renal dysplasia with ectopic ureter orifice opening in vagina;③5 patients (CT 3,MR 2) of Herlyn-Werner-Wunderlich syndrome presented as uterus duplication,oblique vagina septum as well as unilateral renal-ureter dysplasia,which shown as uterus duplex,oblique vaginal septum with hematocolpos,also unilateral renal-ureter agenesis;④2 patients presented as basic abnormalities accompanied with mesonephric residual cyst,CT showed one with uterus duplex and unilateral renal-ureter agenesis with ipsilateral mesonephric residual cyst,MRI showed as the other one with Herlyn-Werner-Wunderlich syndrome combined with mesonephric residual cyst opening in vagina;⑤MRI showed 1 patient with basic abnormalities and a nephrogenic adenoma,which demonstrated as uterus duplex combined with left renal-ureter agenesis,and a tumor on the left wall of bladder accompanied with endometriosis.Conclusion Further classification into 5 types from simple to complex based on uterus duplication combined with unilateral renal-ureter dysplasia with/without other associated malformations is helpful to the diagnosis and treatment of these abnormalities.
