Imaging of the uterovaginal anomalies

Abstract

ObjectiveTo assess the role of different imaging modalities including ultrasonography, hysterosalpingogram, and magnetic resonance imaging in detection of variable Müllerian anomalies. Preoperative proper diagnosis data about Müllerian anomalies necessary for clear indications of how and when to operate. Patients and methodsA retrospective MRI study of 34 patients was done in the period from February 2008 to February 2010, their age ranging from 3 months to 38 years (mean 24 years), with uterovaginal anomalies. Ultrasonography was performed for all cases; HSG was performed in 16 cases before MRI imaging. ResultsMRI is the most reliable method for evaluating uterovaginal anomalies, particularly in pediatrics and virgins. MRI is an accurate examination for identification and categorization of MDAs and should be carried out prior to any surgery, in this study MRI allowed correct diagnosis of 34 uterine anomalies (accuracy 100%) whereas US was correct in 30 out of 34 cases (accuracy 88%). HSG had a limited role as cannot be preformed for virgins, and cannot identify non-communicating horns in unicornuate cases. ConclusionMRI is the examination of choice in uterovaginal anomalies. Endovaginal ultrasound cannot be preformed for children or females who have never had sexual intercourse. TAUS have not proved completely reliable in Müllerian duct anomalies.
