Rationale: Gout in the spine is very rare. The clinical symptoms of the spinal gout are various and lack of specificity. The authors report a case of spinal gout causing lumbar stenosis. We never find such wide-invasive spinal gouty lesion in the published studies. Patient concerns: A 68-year-old male had low back pain radiating to bilateral lower limbs, accompanying with intermittent claudication that lasted for 3 months and aggravated 5 days ago. Diagnoses: Spinal gout, lumbar stenosis. Interventions: The patient underwent L2-L4 laminectomy, L2/3 L3/4 an d L4/5 discectomy and transforaminal lumbar interbody fusion with pedicle screw fixation. Outcomes: Dual-energy computed tomography detected extensive tophaceous deposits in L1/2 L2/3 L3/4 and L4/5 lumbar discs as well as the posterior column, especially L2-L3 and L4-L5 facet joints. During the surgery, we found a mass of chalky white material at the posterior column of L3 to L5 vertebral bodies, which also involved the intervertebral discs. Pathological examination confirmed the diagnosis of spinal gout. Lessons: Although spinal gout is thought to be rare, the diagnosis should be considered if the patient had severe back pain and a history of gout. Dual-energy computed tomography is highly recommended for these patients.
