Abstract

Osteonecrosis (ON) is a common comorbidity in gout; however, avascular ON of multiple sites is unusual. Multifocal ON is defined as osteonecrotic lesions affecting three or more separate anatomic sites. We report a case of a 31-year-old woman diagnosed with gout, who had multifocal ON. Initially, she was treated with benzbromarone, colchicine, and meloxicam. Two years later, she developed severe tophi and was diagnosed with chronic renal failure. Magnetic resonance imaging (MRI) of both legs revealed bilateral ON of the femoral head. She underwent bilateral hip replacement surgeries. After two years, she had pain and limited movements in the left shoulder, with tophi identified via dual-energy computed tomography. Despite management with non-steroidal anti-inflammatory drugs, colchicine, and prednisolone, she had persistent shoulder pain. MRI of the left shoulder revealed ON. She therefore underwent left shoulder replacement surgery. Following the case report, we review the literature on multifocal ON with gout.
