CTICasesRadiation-induced osteitis
Imaging findings
Chest CT in a breast cancer patient post-lumpectomy and radiation therapy shows extensive, exuberant periosteal new bone formation and hypertrophic bridging bone involving multiple adjacent ribs, associated with severe localized chest wall pain.
Key takeaways
Radiation-induced osteitis can present as chronic bone remodeling with hypertrophic, dense periosteal reaction and bridging osteophyte formation. This can mimic tumor recurrence but represents a benign radiation complication, which can cause significant pain.
