Abnormal chest skiagram in a normal individual a case report on orphan lung disease – Pulmonary alveolar microlithiasis

Abstract

Pulmonary alveolar microlithiasis (PAM) is a rare inherited disorder of sodium phosphate cotransporter which causes accumulation of microliths in alveoli. This is a case report of a 46-year-old female, came for surgical fitness for laparoscopic cholecystectomy with abnormal chest skiagram. Chest skiagram showed typical sand storm appearance. Since the patient had no respiratory complaints, high-resolution computed tomography chest was taken which showed diffuse micronodular calcifications suggestive of PAM.
