An interstitial pattern with relevant clinical context

A fictional thin-section chest CT shows basal and subpleural reticular change, traction bronchiectasis and honeycombing. The request mentions a connective-tissue disorder, but the trainee initially labels the finding idiopathic pulmonary fibrosis solely from the CT pattern. No complete exposure history, pulmonary assessment, prior imaging or multidisciplinary discussion is supplied. The supervisor asks the trainee to separate a morphological pattern from a complete etiological diagnosis and to consider the effect of the clinical information. The case also lacks a measured lung-function trend or a treatment-response assessment. It asks for a useful radiological formulation rather than a medicine recommendation or a promise that one CT appearance predicts every person's course.
