Chondrocalcinosis or cartilage calcification is calcification (accumulation of calcium salts) in hyaline cartilage and/or fibrocartilage.[1] Chondrocalcinosis is an observation that can be visualized through diagnostic imaging tests such as X-rays, CT, MRI, and ultrasound[2].

Causes[edit]

Buildup of calcium phosphate in the ankle joints has been found in about 50% of the general population, and may be associated with osteoarthritis.[3]

Another common cause of chondrocalcinosis is calcium pyrophosphate dihydrate crystal deposition disease (CPPD).[4] CPPD is estimated to affect 4–7% of the adult populations of Europe and the United States.[5] Previous studies have overestimated the prevalence by simply estimating the prevalence of chondrocalcinosis regardless of cause.[5]

A magnesium deficiency may cause chondrocalcinosis, and there is anecdotal evidence that magnesium supplementation may reduce or alleviate symptoms.[6] In some cases, arthritis from injury can cause chondrocalcinosis.[7] Other causes of chondrocalcinosis include:[4]

Diagnosis[edit]

Chondrocalcinosis can be visualized on projectional radiography, CT scan, MRI, ultrasound, and nuclear medicine.[1] CT scans and MRIs show calcific masses (usually within the ligamentum flavum or joint capsule), however radiography is more successful.[1] At ultrasound, chondrocalcinosis may be depicted as echogenic foci with no acoustic shadow within the hyaline cartilage.[8] As with most conditions, chondrocalcinosis can present with similarity to other diseases such as ankylosing spondylitis and gout.[1]
