Presentation often mimics gout (“pseudogout”).
Acute CPPD: pain and swelling of ≥1 or more joints; knee involved 50% of the time; ankle, wrist, toe, and shoulder are also common.

Gouty (uric acid) tophi in a middle-aged woman with longstanding gout
<bold>FIG. 4.4.</bold> This "chalky" substance was aspirated from a patient's inflamed olecranon bursa, an appearance that is virtually diagnostic of tophaceous gout.

Chronic tophaceous gout involving the hands and wrists.
<bold>Fig B 10-17. Gout.</bold> Two examples of typical rat-bite erosions about the first metatarsophalangeal joint (arrows). The cystlike lesions have thin sclerotic margins and characteristic overhanging edges.

<bold>Fig B 10-18. Gout.</bold> Diffuse deposition of urate crystals in periarticular tissues of the hand produce multiple large, lumpy soft-tissue swellings representing gouty tophi. Note the erosive changes that typically involve the carpal bones and the distal interphalangeal and metacarpophalangeal joints of the fifth digits.
