Patient Data

Age: 30 Years
Gender: Male

Calcification is seen involving the triangular fibrocartilages on both wrists.

Case Discussion

Chondrocalcinosis is a term used to describe the deposition of the calcium (mainly calcium pyrophosphate dihydrate; CPPD) within articular cartilage. It may be due to different metabolic disorders.

In this case, no definite etiology could be found and the clinical diagnosis is suggestive of being a familial chondrocalcinosis in the absence of clear other etiologies by the clinical examination and laboratory results.

Generally speaking, causes of chondrocalcinosis may include: hypercalcemia, hypomagnesemia, hypothyroidism, acromegaly, gout, and Wilson disease.
