Extensive honeycombing throughout both lungs in a subpleural and basal distribution with consequential tractional bronchiectasis.

This case of severe pulmonary fibrosis demonstrates extensive honeycombing of the lungs in a definite UIP pattern.
The potential causes of usual interstitial pneumonia (UIP) are long, with idiopathic pulmonary fibrosis being the most common.
