Sarah Lafond MD, Presenter: Nothing to Disclose

Juliana Marcela Bueno MD, Abstract Co-Author: Co-author, Oxford University Press

The purpose of this exhibit is to help the learner: Review the basic anatomy of the lung parenchyma as seen on HRCT. Gain understanding on pathophysiology of the different entities that manifest with pulmonary micronodules.  Be able to apply an effective, up to date, diagnostic algorithm when approaching these entities based on imaging findings.  This is important to re-evaluate since the last comprehensive review was performed nearly 10 years prior. Identify new pulmonary pathologies that should be included in the differential diagnosis of  micronodules, including establishing the novel term "arterial tree-in-bud" as a diagnostic consideration.

Review of the anatomic components of the lung parenchyma, specifically emphasizing the secondary pulmonary lobule, as seen on HRCT.  Diagrams HRCT images Anatomic-pathologic correlations of micronodular lung diseases. Examples of HRCT findings of each entity. Updated diagnostic algorithm to micronodular diseases.
