Malignant melanoma of mandibular gingiva; the usefulness of fat-saturated MRI.
Case report of a histologically validated malignant melanoma affecting the mandibular molar gingiva in a 31-year-old woman. Tumour was evaluated by magnetic resonance (MR) imaging at 1.5-T, spin-echo 3 mm slice thickness with T1-weighted and fat-saturated T1-weighted images. The fat-saturated T1-weighted images demonstrated the lesion more clearly than conventional T1-weighted images.
