The role of magnetic resonance imaging in the rare pathologies of the vulva.

Pathologies of the vulva encompass a wide range of mesenchymal and epithelial benign and malignant lesions. Suspicion is raised by non-specific symptoms or clinical findings detected during routine gynecological examinations, and histopathology is essential for the diagnosis. The role of imaging has often been limited, but it can be essential in guiding treatment and, in some cases, in helping differential diagnosis. In particular, magnetic resonance imaging (MRI) can play a central role in identifying the extent of disease and planning surgical treatment. To this aim, rigorous image acquisition, correct disease evaluation in the context of vulvar anatomy and understanding of the possible differential diagnosis are essential. The aim of this article is to review the role of MRI in the evaluation of rare vulvar pathologies, focusing on different sites of origin, imaging characteristics, and local extent.
