Localised fibrosis produces streaky shadows with evidence of traction upon neighbouring structures. Upper lobe fibrosis causes traction upon the trachea and elevation of the hilar vascular shadows. Generalised interstitial fibrosis produces a hazy shadowing with a fine reticular (net‐like) or nodular pattern (see Chapter 13). Advanced interstitial fibrosis results in a honeycomb pattern with diffuse opacification containing multiple circular translucencies a few millimetres in diameter.
