Diffuse, micronodular lung disease. The high-resolution CT approach. A pictorial essay

Careful HRCT evaluation of the preferential distribution of micronodular lesions within the secondary lobule provides a fundamental contribution in the correct interpretation of the different associated patterns. This paper suggests a modern diagnostic algorithm that, together with clinical-anamnestic data and additional imaging features, is able to provide a definitive diagnosis or to reduce the possible differential diagnoses.
