This is an interstitial lung disease due to asbestos exposure. There is progressive dyspnoea and a strong association with malignancy (adenocarcinoma more likely).
Plain film
• Lower zone fibrosis (due to inhalation gradient)
• Pleural plaques
• Effusions
HRCT
• Initially small, sub-pleural, round or branching opacities a few millimetres from the pleura—this is peri-bronchiolar fibrosis.
• Sub-pleural curvilinear opacities, parallel to the chest wall—may represent atelectasis or be associated with honeycombing later on.
• Late disease is characterised by parenchymal bands and reticulation with distortion of the lung parenchyma and traction bronchiectasis.
• As the disease progresses, there is basal honeycombing, appearing similar to UIP.
• No lymph node enlargement.
