[Gout as an unusual cause of pelvic pain]

Abstract

An 89-year-old woman was admitted for high fever and debilitating pelvic pain, notably in the pubic area. Physical examination revealed multiple gouty tophi in her hands and feet. Laboratory investigation revealed severe leukocytosis and a sharply increased C-reactive protein level. The patient was treated with broad-spectrum antibiotics in view of the possibility of a serious bacterial infection, but there was no clinical effect. CT of the pelvis revealed an osteolytic process and a mass anterior to the pubic symphysis. Histological investigation of a biopsy revealed an inflammatory infiltrate with signs of gout. Culture of the biopsy specimen was negative. The diagnosis was confirmed by the finding ofneedle-like urate crystals under the polarizing microscope. After treatment with colchicine and later with prednisone, the symptoms disappeared. She was given uric acid-lowering therapy with allopurinol as a preventive measure.
