Pulmonary alveolar microlithiasis in a patient with rheumatic valvular heart disease.

Pulmonary alveolar microlithiasis is a rare disease characterized by widespread intra-alveolar calcification of both lungs that is asymptomatic in the early stages. The disease typically follows a protracted course, and death can occur in 5 to 41 years after the initial diagnosis. Rheumatic fever is a multisystemic inflammatory disease that afflicts the child and juvenile population, and it is still very common in developing countries. Valve failure is the condition most linked to increased morbidity and mortality rates in this population and is the most severe complication of rheumatic fever, with consequent onset of chronic heart valve disease. We present a case of a female patient with a potential diagnosis of pulmonary alveolar microlithiasis with concurrent rheumatic valvular disease.
