Congenital and acquired conditions of the vulva and vagina on magnetic resonance imaging: a pictorial review.

Magnetic resonance imaging (MRI) has become an established imaging modality for characterizing pelvic pathology, chiefly because of superb contrast resolution and lack of ionizing radiation. In recent years, MRI has been used to stage vulval and vaginal malignancies and assist detection of recurrence. It has also proved useful in the characterization of Müllerian duct anomalies. We review the typical imaging characteristics on MRI of congenital and acquired conditions involving the vulva and vagina.
