Figure 7 (A-F): Ill-defined mass lesion (star) extending along the anterior and left alveolar margins of the mandible with infiltration of bilateral genioglossus muscles, the lingual septum, bilateral sublingual spaces, left masticator space, left submandibular gland, and left geniohyoid muscle inferiorly. The lesion appears isointense on T1 (A), hyperintense on T2 (B), and hyperintense on STIR (C and D) showing contrast enhancement on T1 + c images (E and F). There is sparing of the mylohyoid muscle. Axial T2-weighted fat-suppression image (B) reveals an ill-defined heterogeneous signal intensity nodular mass lesion involving the anterior tongue on left side. It crosses midline anteriorly and involves genioglossus and geniohyoid. Coronal STIR image (D) shows tumor infiltration of the floor of the mouth. Note the involvement of ipsilateral mylohyoid muscle (short arrow) and normal contralateral mylohyoid. Note the tumor infiltration into bilateral sublingual glands (long arrows) on T2FS axial image (B)
