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.
