Acute Eosinophilic Monoarthritis in a Patient with Toxocariasis / 대한내과학회지

ABSTRACT

Eosinophilic synovial effusion is rarely observed in patients with inflammatory nature of synovial fluid, and the differential diagnosis includes parasitic arthritis. Toxocariasis is the one of the most common forms of helminthiasis worldwide and has been reported as a common cause of peripheral blood eosinophilia in Korea. However, joint involvement has been rarely reported in adults with toxocariasis in the English-language literature. Here, we report the first Korean case of a female presenting with acute monoarthritis with an increased number of eosinophils in the peripheral blood and synovial fluid, who was finally diagnosed with toxocariasis.
