RESUMEN
Objective To assess the value of MRI in diagnosis of Herlyn-Werner-Wunderlich syndrome (HWWS).Methods MR images of 10 patients with HWWS confirmed surgically and pathologically were analyzed retrospectively.The classification of HWWS on MRI was discussed.Results The 10 patients were included 4 cases of type Ⅰ,3 cases of type Ⅱ and 3 cases of type Ⅲ.All of them were complicated with ipsilateral renal agenesis.Eight cases were complicated with didelphic uterus and double cervix,2 were complicated with complete septate uterus.Type Ⅰ showed the complete oblique vaginal septum,hematocele in the oblique septum cavity and contralateral uterine cavity.Type Ⅱ showed the oblique septum cavity was connected with main vaginal through the hole of septum.Type Ⅲ showed the oblique septum cavity was connected with main vaginal through the cervical fistula.The prognosis were good in 8 patients.One patient occured obvious dysmenorrhea postoperation and MRI reminded right ovarian endometriosis cyst.One patient occured gusty hypogastralgia,and MRI reminded pelvic inflammation.Conclusion MRI can definitely diagnose and classify HWWS,and can provide useful information in the treatment of HWWS.
