Radiation-induced sarcomas can develop in irradiated tissues without a specific site preference. The average time between radiotherapy and onset of such sarcomas is typically reported to be 10 to 12 years. Here we have the radiologic features of a 71-year-old-female patient with facial asymmetry on the right side. She presented with history of squamous cell carcinoma of the right hemimandible, for which she underwent surgery and radiation therapy 20 years ago. Contrast-enhanced, soft-tissue window computed tomography revealed an ill-defined, expansile, low-attenuation, mixed-density, lytic lesion in the right mandible, with effacement of the fat planes.</div></div><div><h3>Differential Diagnosis</h3><div>Differential diagnosis included recurrent squamous cell carcinoma, lymphoma, salivary gland tumors and soft-tissue sarcomas.</div></div><div><h3>Diagnosis and Management</h3><div>After the work-up of this patient, a diagnosis of radiogenic osteosarcoma was made on the basis of histopathology and associated history. Surgical resection of the tumor was performed with clear margins. Adjuvant chemotherapy was provided since the tumor was larger than 5 cm in diameter. The prognosis of the tumor is poor, and the patient continues to be followed up.</div></div><div><h3>Conclusions</h3><div>Although radiation-induced sarcomas are rare, their incidence has risen because of the increased use of radiation therapy. Radiation therapy is commonly used to treat squamous cell carcinoma, the most common primary malignancy in the head and neck region. It is critical to consider the potential occurrence of radiation-associated sarcoma in a patient presenting with a painful swelling in a previously irradiated area. Even though these lesions appear within the second decade post-radiation, they can appear well over 30 years as well. Continued monitoring is advised for early intervention should this complication develop.

Computed tomography (CT) is the modality of choice to evaluate the TMJ for osseous degenerative changes. Considering that limitation of mouth opening is a frequent manifestation of many TMDs, protocols for TMJ imaging traditionally have included views in the open and closed positions to assess condylar movement relative to the crest of the articular eminence.

The pilot phase includes 22 subjects. The range of motion from the clinical examination was recorded and extent of condylar translation was assessed on the CBCT scans. Condylar movement was scored as “limited” when translation stopped before the crest of the articular eminence and “positive” when the condyle reached or went beyond the crest of the articular eminence.</div></div><div><h3>Results</h3><div>There was concordance in assessment between clinical mouth opening and radiographic condylar translation in 7 of 22 subjects (32%).
