Radiation myelopathy visualized as increased FDG uptake on positron emission tomography.
A woman with a history of desmoid tumor involving the T9-T10 vertebrae was treated with local irradiation. After treatment, she developed tingling sensations in both legs. An FDG PET study demonstrated focally increased activity posterior to the vertebral bodies at the levels of T9-T10, which was vertical in orientation, corresponding to the location of the spinal cord at this level. This finding is consistent with the clinical suspicion of radiation myelopathy.
