Presentation
Known to the respiratory clinic with chronic breathing problems. No occupational history of significance.
Patient Data



Small volume lungs with bilateral increased interstitial markings, most pronounced peripherally, without a zonal predominence.



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