Two crystal compounds—monosodium urate and calcium pyrophosphate dihydrate—can accumulate in connective tissue and/or joints and can present clinically in several ways. The authors discuss the typical patterns seen with each of the arthropathies induced by these crystals, the options available for treatment, and, in the case of gout, ways for preventing recurrence. They also describe identifying radiographic and microscopic characteristics and provide representative illustrations.
