Abstract
Tophaceous deposition of calcium pyrophosphate dihydrate (CPPD) crystals is considered unusual as is deposition within tendon sheaths. Associated tendon rupture is described but is rare. We report a lady with tophaceous CPPD deposition at the wrist, a previously unreported site. Contrary to previous cases, this occurred in the setting of symptomatic, polyartic-ular, pyrophosphate arthropathy. An additional point of interest was development of associated extensor tendon rupture with features favouring a non-inflammatory mechanism of tendon damage.Keywords
