Axial CT of the chest at the level of the aortic arch reveals centrilobular nodules, ground-glass opacities, and mosaic attenuation (likely due to air trapping in this context) and bronchial wall thickening. In the context of a patient with rheumatoid arthritis a diagnosis of follicular bronchiolitis is likely.
