[Magnetic resonance imaging of congenital vaginal anomalies]

To describe the magnetic resonance (MR) imaging manifestations in vaginal anomalies, and to discuss the utility and limit of MR imaging in diagnosis of this abnormality.

Nine female patients with congenital vaginal anomalies who required surgical intervention were studied. MR imaging and ultrasound of the pelvic was performed before surgery. MR imaging features were retrospectively analyzed correlating with surgery.

The vaginal anomalies were categorized into three groups: (1) congenital absence of the vagina and uterus, i.e. Mayer-Rokitansky-Küster-Hauser syndrome (MRKH syndrome) (n=3); (2) vaginal atresia (n=2); and (3) transverse vaginal septum (n=2). There was also one case of absence of vaginal with complicated urinogenital abnormality, and 1 case of obstructed hymen.

MRI is a reliable method for evaluating vaginal anomalies. An accurate MRI examination can be helpful for surgical management.
