[...]. Radiation-Induced Osteonecrosis of the Shoulder. CTICases. Published September 11, 2020. https://cticases.com/c/d8f47
Imaging findings
Chest radiographs and shoulder CT show severe, progressive destruction and osteonecrosis of the distal clavicle, humeral head, and scapula, developing 25 years after high-dose (60 Gy) radiation therapy for a shoulder liposarcoma.
Key takeaways
Radiation-induced osteonecrosis is a late complication of high-dose radiotherapy. It typically manifests decades after treatment as severe, progressive destruction, cortical thinning, and crumbling of all bones in the treatment pathway, mimicking neuropathic joint disease.
