Calcium pyrophosphate dihydrate crystals

Calcium pyrophosphate dihydrate (CPPD) crystals are needle-shaped particles that can form in joints, often causing pain and inflammation. When they accumulate in the cartilage and joint tissues, they may trigger a condition called pseudogout, which mimics gout but is caused by these crystals. The presence of CPPD crystals can result from aging, joint wear, or other metabolic factors. Their formation leads to joint swelling, discomfort, and sometimes damage if untreated. Diagnosing involves analyzing joint fluid under a microscope to identify the crystals, which helps guide appropriate treatment for symptom relief.
