Pseudogout?,”Attacks of pseudogout often occur in the setting of trauma, surgery, or medical illness. PAtients with pseudogout present with acute pain, swelling, redness, and limited motion of the involved joint (s), with the knee being the most commonly affected (> 50% of cases). Fever, leukocytosis with a left shift, and chondrocalcinosis (calcified articular cartilage) may also occur in pseudogout. Synovial fluid analysis is critical for distinguishing between gout and pseudogout. The identification of rhomboid
positively birefringent crystals of synovial fluid analysis is diagnostic of pseudogout.”
