Acute gout of the right sacroiliac joint.

An eighty-year-old woman suffered from acute idiopathic gout of the right sacroiliac joint and tophaceous deposits in two fingers of her right hand. Hyperuricemia and findings consistent with gout detected by histological examination of a biopsy specimen taken from the digital nodules supported the diagnosis. The radiological workup revealed osteolytic changes at the bases of the phalanges in Roentgenograms of the feet. Various aspects of the very rare incidence of sacroiliac gout are discussed.
