An Unusual Cervical Mass in the Hyoid Bone: Intermediate-Grade Chondrosarcoma

Figure 3

(a) Axial fat-sat T2 MRI image shows marked hyperintense mass with lobulated contours (arrows). There are metastatic lymph nodes within the left submandibular area (open arrow) and both sides of the neck lymph node chain (asterisk) with similar signal characteristics. (b) Axial T1 MRI image demonstrates effacement of the fat planes between the mass (M) and the left submandibular gland (S). (c) Coronal contrast-enhanced fat-sat T1 image reveals that the mass has an heterogeneous peripheral and central enhancement with some cystic-necrotic components (arrows).
