Presentation
Patient with progressive dyspnoea especially on exertion. Under investigation for COPD due to chronic exposure to smoke from a wood stove.
Patient Data
In the upper lobes, there are some discrete centrolobular ground glass nodules.
There is extensive areas of air trapping on both lungs in the expiratory images.
Case Discussion
In the inspiratory axial plane, one can see some discrete centrolobular ground-glass nodular opacities in the upper lobes. In the expiratory phase, there are extensive areas of air trapping.
The imaging and clinical aspects are typical of respiratory bronchiolitis, most often secondary to smoking habits, including indirect smoking.
Hut lung usually manifests as respiratory bronchiolitis on CT images. It is secondary to the inhalation of gases produced by the combustion of biomass in enclosed homes.
In Brazil, especially in the colder southern states, the frequent use of wood stoves to cook and heat the house is sometimes a cause for Hut Lung.
