Figure 5 (A-F): Mass lesion (star) involving the alveolar margin of the mandible in the midline extending along the lingual septum and genioglossus muscle with infiltration of the sublingual spaces anteriorly. The lesion appears isointense on T1 (A), heterogeneously hyperintense on T2 (B), and hyperintense on STIR (C and D) showing contrast enhancement on T1 + c images (E and F) and a central focus of nonenhancement— suggestive of necrosis. Axial T2 weighted fat-suppression MR image (B) demonstrates a bulky enhancing tumor in genioglossus of anterior tongue extending into anterior alveolar margin of mandible causing erosion of occlusal cortices of mandible and enhancement in the marrow (short arrow). Sagittal T1 + c image (F) shows tumor invading the floor of the mouth (long arrow). There is sparing of the mylohyoid muscle inferiorly
