Radiologic-Pathologic Pattern | High resolution chest tomography findings |
Usual Interstitial Pneumonia (UIP) | Reticulations Honeycombing Subpleural, basal predominance Absence of features that are diagnostically inconsistent with UIP |
Non specific interstitial pneumonia (NSIP) | Ground glass opacities ± intralobular reticulation, Traction bronchiectasis, Absence or minor honeycombing, Bilateral, symmetrical lesions Lower lobes predominance with sparing of the dorsal subpleural band |
Organized pneumonia (OP) | Consolidation ± ground glass opacities, “halo sign”, subpleural predominance peribronchovascular distribution Migratory character |
Lymphocyte interstitial pneumonia (LIP) | Centrilobular and subpleural nodules, Ground glass opacities Thickening of the septal and bronchovascular bundles Perilymphatic distribution Thin-walled Cysts |
