Table 1 Classification of müllerian duct anomalies

From: Herlyn-werner-wunderlich syndrome: MRI findings, radiological guide (two cases and literature review), and differential diagnosis

MULLERIAN AGENESIS OR HYPOLPLASIA a) vagina b) cervix c) fundus d) fallopian tube e) combined agenesis or hypoplasia (two or more findings from classes I-A through I-D)
UNICORNUATE UTERUS (Agenesis or hypoplasia of one of the two Mullerian ducts) • rudimentary horn with an endometrial cavity that communicates with the (single-horned) uterus; • rudimentary horn with an endometrial cavity that does not communicate with the uterus; • rudimentary horn with no endometrial cavity; no rudimentary horn
UTERUS DYDELPHYS (Failure of lateral fusion between vagina and two Mullerian ducts)  
BICORNUATE UTERUS (Incomplete fusion of uterine horns at the level of the fundus) a) complete (septum extends to the internal or external os); b) partial (septum is confined to the fundal region)
SEPTATE UTERUS (Incomplete or absent resorption of uterovaginal septum) a) complete (septum extends to the internal os); b) partial (septum does not reach the internal os)
ARCHUATE UTERUS (Light indent of the fundus of the uterus due to almost complete resorption of the uterovaginal septum)  
UTERUS EXPOSED TO DIETHYILSTILBESTROL-RELATED UTERINE ANOMALIES a) T-shaped uterus; b) T-shaped uterus with dilated horns; c) Uterine hypoplasia
