Diagnosis With Brief Discussion

Samsung Medical Center, Seoul Korea
Imaging Findings
Chest PA shows patchy consolidations and ground glass attenuations in left mid and lower lung zones.

Thin-section CT shows central ground glass attenuation with peripheral airspace consolidations of crescentic or ring shape along peribronchovascular distribution in multifocal areas of both lungs.
Discussion
BOOP is a clinicopathologic entity characterized clinically by a disorder with systemic symptoms such as cough, sputum and pathologically by the presence of granulation tissue within the respiratory bronchioles and alveolar ducts with patchy areas of interstitial inlammatory cell infiltration largely of mononuclear cells and foamy macrophages. Typical high-resolution CT findings of the disease are bilateral areas of airspace consolidation (seen in 80% of cases) and ground-glass opacity (in 60% of cases), small, ill-defined nodules (30% to 50% of cases) at the subpleural and/or peribronchial regions. Honeycombing is usually absent. The reversed halo sign appears relatively specific to make a diagnosis of cryptogenic organizing pneumonia on CT.
