1. Bibasilar reticular abnormalities with areas of intervening traction bronchiectasis and minimal ground-glass opacity but no honeycombing noted.
These findings are nonspecific but raise concern for interstitial fibrotic lung disease.
The imaging findings suggest a UIP versus NSIP pattern.
Clinical correlation isrecommended with any history of connective tissue disorder,occupational or domestic exposures or potential drug toxicity.
2. No lobar pneumonia, pneumothorax or pleural effusion.
Pathology
- The lung parenchyma is extensively fibrotic with fibrocystic changes. The interstitium shows only scant chronic inflammatory infiltrate, with a predominance of plasma cells. Fibroblastic foci are vanishingly rare. No granulomas or vasculitis are identified. Findings are consistent with end stage interstitial fibrosis or uncertainty etiology. The plasma cells suggest autoimmune disease.Pulmonary Function Trend ReportDate FVC FEV1 ratio FeF25-75 TLC
