title: Case report: magnetic resonance imaging of vaginal malignant melanoma.
abstract: We report two cases of vaginal melanoma with magnetic resonance imaging findings. The first melanoma was a bilobular polypoid mass with melanotic and amelanotic components, which arose from the lateral wall of the vaginal canal. The melanotic melanoma showed high signal intensity (SI) on T1-weighted images and low SI on T2-weighted images, which was not suppressed by a fat-saturated sequence. Another melanoma showed a pale brown polypoid mass in the vagina, which revealed intermediate SI on T1-weighted images and high SI on T2-weighted images. On fat-suppressed images, both tumors were more clearly demonstrated with high SI.
