Large Lungs
Increased Retrosternal Space
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 and the lateral chest X-ray shows multiple juxtaphrenic lung markings and juxtaphrenic peaks.

51 year old male with HIVCT shows mild upper lobe centrilobular emphysema
The lower images (b and c) are magnifications and show the classical Swiss cheese appearance of emphysema with a few of the areas revealing centrilobular structures (teal arrowheads).

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)

71-year-old female presents with history emphysema
Chest X-ray shows hyperinflated lungs with flattened hemidiaphragms and increase in the retrosternal space and right ventricular enlargement based on the decrease in the retrosternal air space
CT scan confirms the presence of centrilobular emphysema, predominantly in the upper lobes with associated right atrial, right ventricular and pulmonary arterial enlargement. The LA and LV are normal
These findings are consistent with cor pulmonale and pulmonary hypertension, secondary to emphysema.

Emphysema Upper Lung Fields
Enlarged Group of Secondary Lobules
Thickened Irregular Interlobular Septa

51-year-old female smoker with a history of COPD asthma and pulmonary hypertension presents with progressive dyspnea. Axial CT through the upper lung fields shows extensive changes of centrilobular emphysema and an expanded group of secondary lobules noted in the right upper lobe Path confirmed a diagnosis of DIP

Fissural Changes from Traction

51-year-old female smoker with a history of COPD asthma and pulmonary hypertension presents with progressive dyspnea. Axial CT through the upper lung fields at the level of the carina shows extensive changes of centrilobular emphysema and ground glasses changes in the anterior segments ? right more prominent than the left. In addition there is irregularity of the right major fissure (lower panel) seemingly as a result of the enlarged secondary lobule, and stress on the fissure by the interlobular septa. Path confirmed a diagnosis of DIP

51-year-old female smoker with a history of COPD asthma and pulmonary hypertension presents with progressive dyspnea. Axial CT through the upper lung fields at the level of the carina shows progression from extensive centrilobular changes to ground glass changes in the left anterior segment, and diffuse ground glass changes in the lower lobes. In addition, there is irregularity of the right major fissure (lower panel) seemingly as a result of the enlarged secondary lobule, and stress on the fissure by the interlobular septa. Path confirmed a diagnosis of DIP
