Background: Fibroepithelial stromal polyp (FESP) is a rare benign mass, usually presenting at the vagina. Herein we report, to our knowledge, the first case of contrast-enhanced magnetic resonance imaging (MRI) with diffusion-weighted images of a giant vulvar FESP, and compare the MRI features with the histopathologic results. Case: A 14-year-old girl presented with a huge mass as large as 20 cm that originated from the labium majora. Preoperative MRI showed a polypoid mass consisting of a central stalk and surrounding stroma. Different signal intensities on MRI were correlated with various histopathologic features. The mass was cured by complete excision without remnant lesion. Summary and Conclusion: Contrast-enhanced MRI with diffusion-weighted images can help us differentiate FESP from other vulvovaginal stromal tumors with a complete evaluation of the external and internal structures and the depth of invasion.
