Explain and illustrate the three patterns of micronodular lung diseases (perilymphatic, centrolobular and random distribution) and expose a systematic approach to narrow the differential diagnoses for each one of these three patterns.

1- Definition of micronodular lung disease and brief review of secondary pulmonary lobule anatomy. 2- Presentation of the three patterns of micronodular lung diseases. 3- Diagrammatic reasoning for narrowing the differential diagnoses for each one of the three micronodular lung disease patterns. 4- Résumé of the most common micronodular lung diseases and of some less common but revelant micronodular lung diseases.

Our aim is to present a diagrammatic reasoning for micronodular lung diseases to establish an accurate and short differential.
