Lung cyst formation in lymphocytic interstitial pneumonia: CT features.
OBJECTIVE
We performed this study to identify and characterize the CT findings of lymphocytic interstitial pneumonia (LIP).


METHODS
The CT findings of two patients with LIP were reviewed and correlated with their histologic specimens.


RESULTS
Chest CT of the two patients showed areas of increased attenuation in both lung fields which were associated with nodular and cystic lesions surrounding the peribronchovascular bundles. The most characteristic abnormality identified on CT was the presence of multiple cysts throughout both lungs. Macroscopic findings of lung biopsy specimens included multiple nodular and cystic lesions.


CONCLUSIONS
This description of multiple pulmonary cysts formation in LIP is new.
