Findings:
1. Multiple subpleural areas of honeycombing with cystic spaces outlined by thick fibrous walls, with basal predominance
2. Patchy areas of interlobular septal thickening interspersed with areas of ground glass opacities and normal lung parenchyma
3. Bilateral areas of traction bronchiectasis due to interstitial fibrosis along with architectural distortion of the secondary pulmonary lobule
4. Mild mediastinal lymphadenopathy
Differential diagnosis to be considered are usual interstitial pneumonia and idiopathic pulmonary fibrosis. Histology confirmed the diagnosis of usual interstitial pneumonia/idiopathic pulmonary fibrosis.
The disease maybe complicated by bronchogenic carcinoma. Prognosis is usually poor with only 10 percent to 15 percent of cases responding to steroids, with an average survival of three to six years.
