WIDESPREAD INTERSTITIAL SHADOWING IS USUALLY FIBROSIS and associated with volume loss. Main reason for normal/large volume with fibrosis is usually COPD A few rare causes are HISTIOCYTOSIS,NEUROFIBROMATOSIS, AND LLYMPHANGIOMYOMATOSIS OTHER CAUSES COLLAGEN VASCULAR D ALVEOLITIS UIP RADIATION DRUGS SICKLE, SCLERODERMA
