Educational objective
  • To review female genitourinary system embryology and congenital genitourinary malformations.
  • To show MRI findings of interesting cases of Müllerian anomalies diagnosed in our centre comparing ESHRE-ESHE and the new 2021 ASMR Müllerian duct anomalies classifications.
Topic Review

Congenital uterine anomalies (CUA), also referred Müllerian duct anomalies (MDA), are a complex spectrum of developmental anomalies of the uterus, Fallopian tubes, cervix, and proximal two-thirds of the vagina, that occur between the 6th-11th weeks of gestation. The prevalence of these anomalies is not accurately known (estimated 1-5% of all women and almost one-third of women with a renal anomaly). Still, it is a common cause of amenorrhea, infertility, obstetric complications, and miscarriages.

 

Female genitourinary system embryology

Uterus,fallopian tubes, cervix, and upper vagina arise from müllerian ducts (paramesonephric ducts). In a female fetus, the mesonephric ducts regress in the absence of testosterone, and the...

Conclusions

Accurate classification of CUA is essential for clinicians to provide the most appropriate treatment and counseling to women. MRI is the imaging gold standard because of its multiplanar capability. Radiologists must be aware of updates in the classifications to best describe the spectrum of CUA
