Calcium Pyrophosphate Arthropathy

Calcium Pyrophosphate Dihydrate Crystal Deposition Disease

  • Tophaceous Pseudogout This results due to deposition of calcium pyrophosphate material in a large quantity producing a big pseudotumor which is often painful.[boneandspine.com]

Soft Tissue Calcification
  • It should be included in the differential diagnosis of periarticular soft tissue calcifications because this disease may commonly mimic a bone tumor. Unenhanced CT is the best imaging technique to establish the diagnosis.[ajnr.org]
