CTICasesRadiation-induced rib fractures
Imaging findings
Serial chest CT scans in a lung cancer patient post-stereotactic body radiotherapy show progressive osteolysis and subsequent pathologic fractures of multiple adjacent ribs within the treatment field.
Key takeaways
Pathologic rib fractures are a well-documented complication of stereotactic body radiotherapy for peripheral lung tumors. They arise from radiation-induced osteitis and osteonecrosis within the high-dose treatment field, and should not be misinterpreted as tumor recurrence.
