  • Widespread small centrilobular ground-glass nodules can be noted in both lungs predominantly in the lower lung zones.
  • There is a small patchy consolidation in the perihilar region of the left lower lobe.
  • Diffuse bronchial wall thickening is noted.
  • There is no evidence of significant mucus plugging.
  • There is no pleural effusion.
     

Case Discussion

The patient had a previous thymectomy and was a non-smoker.

The presence of centrilobular ground-glass nodules is typical finding in follicular bronchiolitis due to the hyperplasia of the bronchus-associated lymphoid tissue .

In addition small pulmonary cysts are noted as well, which is a common related finding.
