The Utility of Ultrasound-Guided Synovial Biopsy in the Diagnosis of Crystal-Induced Arthritis
Abstract
The diagnosis of crystal-induced arthritis is routinely established by synovial fluid analysis. However, a synovial effusion is not always present, fluid aspiration is not always possible or practical, and synovial fluid analysis is occasionally subject to false negative results. When there is a high suspicion of crystal-induced arthritis, but crystals are not identified in the synovial fluid, a biopsy of the synovium in search of crystals can assist in making a diagnosis. In this manuscript, we review the utility of ultrasound-guided needle biopsy of synovial tissue in the identification of crystal-induced arthritis, briefly describe the procedure, and recommend best practices for specimen handling and tissue processing.
