MR Imaging of the Female Perineum: Clitoris, Labia, and Introitus.

The female perineum has a complex anatomy and can be involved by a wide range of pathologies. In this article, we specifically focus on the clitoris, labia, and introitus. We discuss the normal anatomy of these structures, the MR imaging techniques to optimize their evaluation, and several common and uncommon entities that may affect them, including benign and malignant tumors, as well as infectious and inflammatory, vascular, iatrogenic, and developmental entities.
