Morphological description
Describe clustering, possible layering, basal or other predominance and accompanying volume loss.
Causes and diagnostic direction
Usual interstitial pneumonia may show this appearance; other fibrosing interstitial diseases can also produce it.
Differential diagnoses
Paraseptal emphysema and traction bronchiectasis can resemble honeycombing; review the complete series.
Pitfalls and limitations
A usual interstitial pneumonia pattern does not automatically establish idiopathic pulmonary fibrosis.
Take-home message
Recognise cystic remodelling, then determine the pattern and cause through multidisciplinary correlation.
