Wang Y, et al. - This study was conducted to assess the pelvic magnetic resonance imaging (MRI) findings of Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome and summarize the typical and atypical characteristics. Researchers performed a retrospective analysis of 201 consecutive MRKH individuals. They examined pelvic MRI by two experienced gynecological radiologists in consensus. They explored characteristics including the morphology, signal pattern and volumes of the uterine rudiments, location, and volume of the ovaries, and the degree of vaginal dysgenesis. As per the results, MRKH patients typically present bilateral uterine rudiments combined with a fibrous band and normally located ovaries. It was demonstrated that the uterine rudiments are generally small with only one-layer differentiation, a subset of which might be large and showed other atypical presentations, involving two- or three-layer differentiation or even hematometra. Abnormally located ovaries are not rare.
