● Rare, diffuse bilateral microliths or calcospherites with prominent rings within alveoli of otherwise normal lung
● 1/3 of cases are familial, may have autosomal recessive inheritance
● Most cases asymptomatic with benign course, but cough and more severe disease reported
● Microliths may be confused with more common entitity of corpora amylacea
● Microlithiasis is more extensive
● Corpora amylacea may have rings but lack calcification, and examination of Congo red stained material with polarized light reveals a Maltese cross pattern
