Osteoradionecrosis of the right ramus of the mandible in a 70-year-old woman 4 years after ChT/RT for a right palatine tonsil cancer. Axial CT image (a) shows the loss of spongiosa trabeculation and several cortical breakings (black arrowheads) of the right ramus of the mandible. The corresponding MR slice of the same area (white arrowheads) shows heterogeneous and slightly hyperintense signal on axial T2-weighted (b), with low signal on axial T1-weighted (c), and subtle but diffuse enhancement in the bone and adjacent soft tissues, like the right masseter muscle (asterisk), in post-contrast axial T1-weighted image (d). M, mandible; T, tongue
