case_images: The maxillofacial-enhanced MRI performed 10 months after the completion of chemotherapy indicated that the range of nodular and patchy fat-saturated T2 signal in the tongue's body and base increased, demonstrating uneven and obvious enhancement with an unclear boundary involving the geniohyoid, left geniohyoid, and mylohyoid muscles ( Figures 2 ,  3 ).
