Uterovaginal anomalies are associated with a high incidence of decreased fertility and multiple obstetric problems. These anomalies are caused by alterations in development or fusion of the müllerian ducts. Uterovaginal anomalies are classified into three types: dysgenesis, vertical or lateral fusion defects, and unusual configurations. Systematic analysis of magnetic resonance (MR) images allows accurate morphologic demonstration and classification of uterovaginal anomalies, thereby indicating the appropriate treatment. The following parameters are recorded in MR images: uterine size, external fundal contour, intercornual distance, zonal anatomy, and presence of uterine or vaginal septa. Associated pelvic lesions or renal anomalies are to be reported. MR imaging allows diagnosis of obstructive uterovaginal anomalies; determining the site of obstruction is imperative for planning the proper surgical approach. MR imaging techniques, including planes, sequences, and the application of more recent advances, are discussed. Pelvic phase-array coils and endovaginal coils provide detailed images and can be problem-solving tools in complex anomalies. MR imaging findings associated with a variety of uterovaginal anomalies are shown. The author suggests a five-step approach for diagnosing uterovaginal anomalies with MR imaging.
