An 84-year-old male patient, suffering from long-term arthrosis, had been treated for hyperuricemia. Recently, although the serum uric acid test results were normal, the patient had been complaining of pain in the right foot. A TwinBeam Dual Energy (TBDE) CT scan was requested for further evaluation.
