A 51-year-old man with subacute onset interstitial lung disease associated with polymyositis. At the time of initial diagnosis (a), there was a subpleural dense consolidation to ground-glass opacification, accompanied by a decreased lower lobe volume. Then, 13 years later (b), the lesion became more extensive, and the areas of consolidation had changed as an area with reticular and small cystic lesion, some of which resembled a honeycomb lung.
