Answer

Although significant joint effusion is uncommon, arthrocentesis may occasionally be needed to exclude septic arthritis. The joint aspirate demonstrates an exudative fluid with low cell counts and mononuclear predominance. Patients with brucellosis rarely present with acute monoarticular arthritis.
