Pseudogout (Calcium pyrophosphate dihydrate crystal deposition)

Pseudogout, also known as calcium pyrophosphate dihydrate (CPPD) crystal deposition, is a joint condition caused by the buildup of tiny crystal deposits in the cartilage. These crystals trigger inflammation, leading to sudden joint pain, swelling, warmth, and redness, often resembling gout. It commonly affects older adults and knees but can involve other joints. The exact cause isn’t fully understood but may relate to aging, joint wear, or metabolic issues. Diagnosis typically involves joint fluid analysis, and treatment focuses on relieving inflammation and pain through medications and supportive measures.
