A HRCT scan of the chest shows predominantly upper lung cystic changes both subpleural and clustered with a honeycomb appearance superimposed on a background of diffuse ground glass opacification. Typical HRCT findings include patchy scattered areas of ground glass opacity and consolidation that usually involve the perihilar and lower aspects of the lungs. However, case reports of rare findings of multiple honeycomb cystic changes have been reported that are thought to be a result of progressive fibrotic changes from hemosiderin deposition in the interstitium (1). These honeycomb cysts may represent sites of more severe and recurrent alveolar hemorrhage in adults ..
