Rare Acute Polyarticular Gout Disease Detected with 18F-FDG PET/CT.

Abstract

Gout is an inflammatory arthropathy that develops due to the accumulation of monosodium urate crystals in the joints in adults. In approximately half of the cases, it presents as monoarthritis with an acute attack involving the first metatarsophalangeal joint. The first attack is rarely polyarticular. Herein, we present a male patient who presented with swelling and acute pain in the 5^th toe but ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography showed symmetric polyarticular involvement which was mimicking arthritis.
