Abstract

Gout has been recognized for centuries but is also a modern day scourge. It is the most common type of inflammatory arthritis in men and appears to be increasing in both incidence and prevalence (Arromdee et al. in J Rheumatol 29(11):2403-2406, 2002). Despite these facts, few advances have been made in the diagnosis and treatment of gout for over 50 years. Difficult cases of gout challenge available therapeutic options. It is only recently that the Food and Drug Administration has approved febuxostat as a treatment option for patients intolerant of allopurinol. We describe a difficult case of tophaceous gout notable for several reasons: utilization of rasburicase as uricolytic treatment to dramatically reduce tissue urate burden; treatment of gout flares with interleukin-1β inhibition; and quantification of tissue urate with novel dual energy computed tomography technology before and after uricolytic therapy.
