Gouty tophus in a 39-year-old man presenting with a swollen and erythematous toe which was clinically suspected to be an infection. X-ray showed 1st MTPJ erosion at the medial border associated with dense soft tissue swelling (arrow). Dual-energy CT with material decomposition helped differentiate urate crystals (mapped as green, arrowed) from calcium (blue, not present in this case).
