MRI SE T1 coronal planes before (a) and after gadolinium infusion (b); SE T1 axial plane after gadolinium infusion (c). MRI shows a right floor of the mouth tumour with a suspected infiltration of medullary bone in the edentulous site (arrows). CT in coronal (d) sagittal (e) and axial (f) planes shows a suspected infiltration of the cortex (arrows). The histological result indicated that the mandible was free from neoplastic invasion (pathological stage T3).
