Chronic carpal tunnel syndrome caused by covert tophaceous gout: A case report

Figure 2 Magnetic resonance images of the patient’s right hand and wrist. A: Lateral projection; B: Posteroanterior projection; C: Transverse projections. Magnetic resonance imaging revealed a giant mass adhering to the surface of the distal volar radius. The base of the mass was wide (A, B, white arrows). There was also a mass adjacent to the digital flexor tendons at the level of the proximal carpal tunnel. These were pressing on the median nerve (C, red asterisks).
