CT Follicular Bronchiolitis, (aka Bronchiolitis Obliterans), Centrilobular Nodules, Air Trapping, Ground Glass Opacities (GGO) in Upper Lobes
70-year-old female former smoker with long standing history of RA presents with chronic dyspnea.
Axial CT of the chest at the level of the aortic arch reveals centrilobular nodules (b, white arrowheads) , ground-glass opacities, and mosaic attenuation (b, white rings) likely due to air trapping in this context, and bronchial wall thickening (b, c teal rings). There is some irregular thickening of the interlobular septa. In the context of a patient with rheumatoid arthritis a diagnosis of follicular bronchiolitis is likely. However radiologically fibrotic hypersensitivity pneumonitis (HP) is included in the differential diagnosis
