RESUMO
A 90-year-old man was diagnosed with monoarticular arthritis due to pseudogout and Abiotrophia defectiva infection. A. defectiva is recognized as a cause of endocarditis, but is rarely described in septic arthritis. To our knowledge, this is one of the few case reports of septic arthritis due to this organism, and the first in association with pseudogout. This report supports the routine culture of synovial fluid and is further evidence for the role of A. defectiva in septic arthritis.

Musculoskeletal infections are uncommon complications of monosodium urate and calcium pyrophosphate dihydrate (CPPD) crystal deposition disease, and frequently involve gram positive and negative organisms. Tumoral calcinosis (tophaceous pseudogout) is a rare manifestation of CPPD deposition disease. We describe a highly unusual case of an infection by Mycobacterium tuberculosis (TB) of a tophaceous pseudogout nodule in a patient with endstage renal disease. The highly destructive nature of this case of combined CPPD arthropathy and musculoskeletal TB underscores the urgency of diagnosing this infection in susceptible patients from countries with high prevalence rates of TB infection.
