Imaging findings
A patient presenting with a leg fracture and a history of multiple fractures exhibits abnormally dense bones on imaging. The radiographs and sagittal CT reformats show preserved cortex and medullary spaces but a lacy appearance of the bone. This differs from metastatic cancer, where medullary spaces might be effaced.
Key takeaways
This is a case of fluorosis, a condition causing increased bone density with a characteristic lacy pattern, which can lead to multiple insufficiency fractures. The unusual source in this patient was inhalation of fluorocarbon propellants found in canned aerosols used for cleaning computer keyboards.
