• Fig C 5-1 Classic honeycomb pattern in pneumoconiosis. (A) Frontal and (B) lateral views.

• Fig C 5-2 Sarcoidosis. Coarse honeycomb pattern.

• Fig C 5-3 Bronchiectasis (cystic fibrosis). Diffuse increase in interstitial markings radiating in a bronchovascular distribution with tramlines (arrows) and peribronchial cuffing (arrowhead).16

• Fig C 5-4 Diffuse interstitial fibrosis. (A) Frontal and (B) lateral views of the chest demonstrate a coarse reticular pattern indicating pronounced fibrosis. Intervening small areas of lucency produce the appearance of a honeycomb lung, especially in the right upper lobe.

• Fig C 5-5 Pulmonary Langerhans cell histiocytosis. Diffuse honeycomb pattern that is slightly more prominent in the upper lung zones.

• Fig C 5-6 Scleroderma. Coned view of the left lower lung demonstrates a honeycomb pattern, with small emphysematous areas combined with fibrosis and fine nodularity.

• Fig C 5-7 Amyloidosis.

• Fig C 5-8 Neurofibromatosis.
