Desquamative Interstitial Pneumonia (DIP)
Patchy Ground Glass Changes, 

Coronal CT- Desquamative Interstitial Pneumonia Diffuse Ground Glass Changes with Patchy Changes more Prominent at the Lung Bases
60-year-old male smoker with a history of progressive dyspnea. Coronal CT through the posterior lung fields at the level of the vertebral column shows extensive patchy ground glass changes and mosaic attenuation. A few of the secondary lobules show prominent centrilobular nodules reflecting a small airways component but the predominant pattern is an alveolar pattern
Pathology confirmed a diagnosis of DIP

Coronal CT- Desquamative Interstitial Pneumonia Diffuse Patchy Ground Glass Changes and Sparing of the Anterior Segment of the Right Upper Lobe
60-year-old male smoker with a history of progressive dyspnea. Coronal CT through the mid lung fields at the level of the left ventricle shows diffuse patchy ground glass changes and mosaic attenuation. There is sparing of the anterior segment of the right upper lobe.
Pathology confirmed a diagnosis of DIP

Follicular Bronchiolitis and RA

CT Follicular Bronchiolitis,, 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, 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. However radiologically fibrotic hypersensitivity pneumonitis (HP) is included in the differential diagnosis

CT Follicular Bronchiolitis, (BALT), 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

CT Follicular Bronchiolitis,, Bronchial Wall Thickening
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 carina reveals centrilobular nodules, ground-glass opacities, and mosaic attenuation (likely due to air trapping in this context) and bronchial wall thickening . Bronchial wall thickening (b, maroon arrowheads) and irregular septal thickening (b maroon arrowheads) are noted.
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

CT Follicular Bronchiolitis, , Centrilobular Nodules, Air Trapping, Ground Glass Opacities (GGO) in Lower 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 lower lung fields reveals centrilobular nodules, ground-glass opacities, and mosaic attenuation (likely due to air trapping in this context). 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

CT Follicular Bronchiolitis, , Centrilobular Nodules, Air Trapping, Ground Glass Opacities (GGO)
70-year-old female former smoker with long standing history of RA presents with chronic dyspnea.
CT in the coronal plane of the chest at the level of the spine reveals bilateral diffuse changes in the lungs characterized by centrilobular nodules, ground-glass opacities, mosaic attenuation (likely due to air trapping in this context) and 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
