Case report: MR findings of malignant melanoma of the vagina.

ABSTRACT

We report a case in which malignant melanoma of the vagina showed some MR signal changes after radiotherapy. Before radiotherapy, the tumour had slightly high signal intensity on T(1) weighted images and was enhanced after gadolinium-DTPA administration. After radiotherapy, the signal intensity of the tumour increased conspicuously on both T(1) weighted images and fat suppression T(1) weighted images.
