| Abstract | Gout and calcium pyrophosphate crystal deposition disease (CPPD) are common forms of inflammatory arthritis whose prevalence has increased in recent years. Although the identification of monosodium urate crystals (MSU) and calcium pyrophosphate crystals (CPP) in synovial fluid (SF) by polarized light microscopy are the gold standard for diagnosing these diseases, SF analysis is not always available. An early diagnosis and specific treatment, especially in gout, allows avoiding irreversible structural damage, comorbidities, and a severe impact on the quality of life of patients. Musculoskeletal ultrasound (US) is a noninvasive tool that allows detecting aggregates of microcrystals at multiple anatomical sites and helps to establish a specific diagnosis. The objective of this review is to evaluate the applications of US in the diagnosis and clinical management of the main microcrystalline arthropathies. The US has helped improve our understanding of the natural history of the disease, due to its ability to visualize not only soft tissue inflammation and structural damage, but also the characteristics of MSU and CPP crystal deposition. The anatomical sites of crystal deposition are also a key factor for differential diagnosis in different microcrystalline diseases. The US allows establishing an early diagnosis, especially in asymptomatic hyperuricemia, to discriminate with other inflammatory diseases, to assess the extent of microcrystalline deposition and their sensitivity to change after treatment. Given its increasing availability in clinical practice and strong evidence, US is a bedside imaging technique helping clinicians to improve diagnosis and therapy monitoring in their daily practice. |
