CT Emphysema, Paraseptal Emphysematous Changes Bilateral Lower Lobes
65-year-old male with emphysema of the lungs presents with a cough, fever and leukocytosis. CT in the axial plane shows bibasilar paraseptal emphysematous changes and centrilobular changes in the lingula and RUL. Hyperinflation with resultant small heart is noted.

Axial CT – Lady Windermere Syndrome
61-year-old male with a history of treated mycobacterial infections including MAC and chronic cough.
Axial CT at the level of the mid to lower chest shows mildly ectatic segmental airways to the lower, and middle lobe bronchi but significant bronchiectasis to the middle lobe and lingula involving the subsegmental airways. There is a relative paucity of mucus in the ectatic airways. The history of MAC and the distribution of the bronchiectasis in the middle lobe and lingula are reminiscent of the diagnosis of Lady Windermere syndrome

Axial CT- Desquamative Interstitial Pneumonia Heterogeneous Ground Glass Changes in the Lower Lung Fields with Mosaic Attenuation
60-year-old male smoker with a history of progressive dyspnea. Axial CT through the lower lung fields at the level of the left atrium shows diffuse ground glass changes with more prominent heterogeneity and mosaic attenuation (b and c). Some of secondary lobules are expanded, with some with slightly thickened septa and prominent centrilobular nodules likely indicating small airway involvement (c, white ring).

CXR Emphysema and Small Heart
58-year-old male presents with dyspnea. The lungs are hyperinflated with flattening of the diaphragms and increase in the retrosternal space on the lateral examination. The person also has an asthenic build with a relatively straight back and narrow A-P dimension. Frontal CXR shows a small heart with structures of the heart visualized to the right of the midline caused by compression of the low-pressure right atrium. The increased in the retrosternal airspace also compresses the relatively low pressure anteriorly positioned right ventricle. The heart is also lifted off the diaphragm (band c white arrowheads) and results in juxtaphrenic lung markings and peaks below the heart (d, arrowheads)

Axial CT ? Human Herpes Virus 8 and primary Effusion Lymphoma (PEL)
Axial CT scan with contrast of 71-year-old male shows bilateral complex and loculated effusions with thickened enhancing pleura. Pleural tap of the left effusion revealed evidence of lymphoma likely related to the patients underlying herpes virus infection. An entity called primary effusion lymphoma (PEL) is a rapidly progressing non-Hodgkin?s B-cell lymphoma that develops in body cavities

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
