Pulmonary alveolar microlithiasis.

We report a patient with pulmonary alveolar microlithiasis who was admitted to King Abdul-Aziz Hospital, Makkah, Kingdom of Saudi Arabia with chest pain, shortness of breath, dry cough and swelling of lower limbs. The patient underwent chest radiographs and CT scan showing multiple diffuse, almost symmetrical bilateral micronodular opacities of calcific density. The diagnosis was confirmed after percutaneous lung biopsy from the patient. Cardiokinetics, diuretics and oxygen were administered with slight improvement.
