Characteristic appearance of large subcutaneous gouty tophi in magnetic resonance imaging.
The development of multiple large tophi in patients with gout is rare. We report magnetic resonance (MR) and histological features of large subcutaneous tophi in a 32-year-old male patient with no known arthritis. His subcutaneous lesions were confused with a neoplastic process, evaluated by MR imaging, and surgically excised after biopsy. The honeycomb-like appearance on the gadolinium-enhanced images may reflect the characteristic multilobular structure of the tophi composed of avascular urate deposits and surrounding vascularized granulation tissue.
