Magnetic resonance imaging value of primary amenorrhea caused by uterus and lower genital tract dysplasia
Objective To explore the MRI features and diagnostic value in the diagnosis of primary amenorrhea caused by uterus and lower genital tract dysplasia.Method A total of 41 patients with primary amenorrhea due to congenital dysplasia admitted to Beijing Obstetrics and Gynecology Hospital,Capital Medical University from November 2015 to May 2023 were selected.Their clinical manifestations and MRI images were retrospectively analyzed,and the imaging features were summarized.Result 41 patients suffered from primary amenorrhea included 27 cases of MRKH syndrome,2 cases of androgen insensitivity syndrome,6 cases of congenital imperforate hymen,2 cases of congenital cervix atresia and 4 cases of lower part vagina atresia.27 cases of MRKH syndrome showed bilateral rudimentary uteri for 24 cases,unilateral rudimentary uteri for 2 cases and totally absent uterus for 1 case.19 cases were involved with partial vaginal atresia,the rest 8 cases manifested complete vaginal atresia.No uterus and cervix were noted in 2 cases of androgen insensitivity syndrome.And inferior vagina was found in the 2 patients.1 case of gonads located in the bilateral inguinal region,and the other medial to the external iliac vessels with accompanying tumors.6 cases of congenital imperforate hymen manifested vaginal,cervical duct and uterine hemorrhage,1 case combined with tubal hemorrhage.2 cases of congenital cervix atresia were accompanied by vaginal atresia and tubal hemorrhage.4 cases of lower part vagina atresia showed dilation of upper part of vagina,cervical duct and uterine.Conclusion MRI can clearly display dysplasia of uterus and lower genital tract,and identify the pathological location,providing reliable reference information for the next diagnosis and treatment of patients.
