Chondrocalcinosis or cartilage calcification is calcification (accumulation of calcium salts) in hyaline cartilage and/or fibrocartilage.[1] It can be seen on radiography.
Causes
Buildup of calcium phosphate in the ankle joints has been found in about 50% of the general population, and may be associated with osteoarthritis.[2]
Another common cause of chondrocalcinosis is calcium pyrophosphate dihydrate crystal deposition disease (CPPD).[3] CPPD is estimated to affect 4–7% of the adult populations of Europe and the United States.[4] Previous studies have overestimated the prevalence by simply estimating the prevalence of chondrocalcinosis regardless of cause.[4]
A magnesium deficiency may cause chondrocalcinosis, and there is anecdotal evidence that magnesium supplementation may reduce or alleviate symptoms.[5] In some cases, arthritis from injury can cause chondrocalcinosis.[6] Other causes of chondrocalcinosis include:[3]
- Hypercalcaemia, especially when caused by hyperparathyroidism
- Arthritis
- Pseudogout
- Wilson disease
- Hemochromatosis
- Ochronosis
- Hypophosphatasia
- Hypothyroidism
- Hyperoxalemia
- Acromegaly
- Gitelman syndrome
Diagnosis
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.[7] As with most conditions, chondrocalcinosis can present with similarity to other diseases such as ankylosing spondylitis and gout.[1]
