Which XRAY finding is common in Pseudogout?

• A. Lytic lesions
• B. Osteoporosis
• C. Linear Radiodensities
• D. Microfractures

Answer: (C)

In pseudogout, calcium pyrophosphate crystals deposit in articular cartilage and menisci, producing calcification of the cartilage itself. On X-ray this appears as linear radiodense lines along the surfaces of the joint cartilage, a finding known as chondrocalcinosis. This linear calcification is the classic radiographic hallmark of CPPD deposition.

Lytic lesions would suggest bone destruction from tumors or infections, not a cartilage calcification. Osteoporosis shows diffuse bone demineralization, not cartilage calcification. Microfractures are small cracks in bone often related to trauma or osteoporosis, and are not the characteristic feature of pseudogout. The presence of linear radiodensities in cartilage best fits CPPD-related chondrocalcinosis.
