Magnetic resonance imaging findings of fibroepithelial polyp of the vulva: radiological-pathological correlation.
We describe the magnetic resonance (MR) imaging findings in a 20-year-old woman with a fibroepithelial polyp of the vulva. Within the lesion, abundant fibrous tissue was visualized as stratiform hypointense areas on T2-weighted magnetic resonance imaging (MRI) scans. At the center of the attachment site, clustered fatty tissue was revealed as linear hyperintense areas on T1-weighted MRI. A mild degree of edematous stroma including less fibrosis and cellularity was demonstrated as hyperintense areas on T2-weighted MRI and hypointense areas on T1-weighted MRI. Although the MRI findings of fibroepithelial polyps of the vulva are often similar to those of aggressive angiomyxoma, angiomyofibroblastoma, and cellular angiofibroma, a fibroepithelial polyp should be considered when radiological images demonstrate the following features: stratiform hypointense areas surrounded by patchy hyperintense areas on T2-weighted MRI and hyperintense areas on T1-weighted MRI.
