Diffuse hyperdense synovial thickening and fluid involving the distal radioulnar, radiocarpal, intercarpal and carpometacarpal joints is stable in extent when compared to the MRI. These synovial changes again distend the adjacent joint recesses as well as extending into adjacent tendon sheath including the extensor carpi ulnaris. Associated bony erosions are again present with this hyperdense synovial proliferation also extending into these bony defects. Dual-energy CT demonstrates these hyperdensities to contain uric acid.
Conclusion:
Widespread changes of erosive tophaceous gout at the wrist.
