Summary
Tophaceous calcium pyrophosphate dihydrate (CPPD) crystal deposition in the wrist is rare. This case highlights an unusual presentation of symptomatic pyrophosphate arthropathy with tendon rupture.
Area of Science:
- Rheumatology
- Crystal Arthropathies
- Orthopedic Surgery
Background:
- Tophaceous deposition of calcium pyrophosphate dihydrate (CPPD) crystals is uncommon.
- Deposition within tendon sheaths is also unusual.
- Associated tendon rupture is a rare complication.
Observation:
- A case of tophaceous CPPD deposition at the wrist, a previously unreported site, is presented.
- This occurred in a patient with symptomatic, polyarticular pyrophosphate arthropathy.
- Extensor tendon rupture developed, with features suggesting a non-inflammatory mechanism.
Findings:
- The wrist is an unusual site for tophaceous CPPD deposition.
- The deposition was associated with symptomatic, polyarticular pyrophosphate arthropathy.
- Extensor tendon rupture occurred, likely due to non-inflammatory tendon damage.
Implications:
- This case expands the known sites of tophaceous CPPD deposition.
- It underscores the varied clinical manifestations of pyrophosphate arthropathy.
- Understanding the mechanism of tendon damage may inform future treatment strategies.
