Tophaceous pseudogout of the mitral valve.
This report describes a 61-year-old patient on chronic hemodialysis with multiple, left-sided, intracardiac masses causing intermittent coronary obstruction. Mitral valve replacement was performed. Massive deposition of calcium pyrophosphate crystals in and around the valve cusps led to the diagnosis of tophaceous pseudogout (tumoral calcinosis) of the mitral valve.
