Pulmonary alveolar microlithiasis is a rare condition caused by deposition in the alveoli of the lungs by calcific consolidation called calcospherites. Its etiology and pathogenesis are obscure. Osteopetrosis is a heterogeneous group of inheritable conditions with a defect in bone resorption by osteoclasts. We report a case of pulmonary alveolar microlithiasis associated with osteopetrosis, which was diagnosed incidentally by bone high density and generalized osteosclerosis on chest x-ray. Association of these two diseases has not been reported before
