Overview

CT Findings

Findings seen on CT scan are:[1][2]

  • Subpleural and/or peribronchovascular consolidation.
  • Ground-glass attenuation and nodules.
  • Irregular linear opacities.
  • Bronchial wall thickening and dilatation.
  • The reverse halo sign (atoll sign) .[3]


Peripheral and peribroncovascular ground-glass opacities with small areas of consolidation in a patient with cryptogenic organizing pneumonia.[4]
Multiple bilateral subsegmental consolidations and mild bronchial dilatation with bronchial wall thickening in a patient with cryptogenic organizing pneumonia.[5]
