Roentgenographic aspects of calcium pyrophosphate dihydrate crystal deposition disease (pseudogout).
AI Summary
Key Findings
Abstract
A comprehensive review of the roentgenographic features of calcium pyrophosphate crystal deposition disease (pseudogout) is presented. The roentgenographic techniques are reviewed. Those recommended as optimal are as follows: for small peripheral joints, industrial Type M film with contact exposure; for large central joints, direct radiographic magnification (3-4 X) with a microfocus tube. The classic appearances of articular chondrocalcinosis in fibrocartilage, hyaline cartilage, and capsular structures are discussed. Distinctive features of pyrophosphate arthropathy, including the distribution of involvement and the degree of destruction, are emphasized. Finally, the relationship among articular chondrocalcinosis, arthropathy, microscopic crystals, and symptoms is discussed.
