A 55-year-old-male patient had acute lower back pain and radiculopathy with high spiking fever, which indicated pyogenic discitis. Intravenous antibiotics were administered but a high spiking fever and elevated laboratory findings indicated an infection. Therefore, surgery was performed. However, histological diagnosis revealed tophaceous gout. A diagnosis of spinal gout should be considered when there are clinical presentations of acute back pain and fever, especially in patients with acute back pain and a prior history of hyperuricemia or gout.
