Overview
Lung:
Pulmonary hypertension (right ventricular prominence, or loud P2)
enlarged pulmonary trunk (measured at pulmonary artery bifurcation on an axial slice vertical to its long axis)
- enlarged pulmonary arteries
- mural calcification in central pulmonary arteries
- centrilobular ground-glass nodules
- neovascularity: tiny serpiginous intrapulmonary vessels that often emerge from centrilobular arterioles but do not conform to usual pulmonary arterial anatomy
Pulmonary fi brosis (physical and radiographical)
- honeycombing
- traction bronchiectasis
- lung architectural distortion
- reticulation
- interlobular septal thickening:
Shrinking lung (radiograph)
CT chest often shows reduced lung volumes with diaphragmatic elevation +/- occasional basal atelectasis but without any major parenchymal lung or pleural disease
Pleural fibrosis (radiograph)
Pulmonary infarction (radiograph)
wedge-shaped (less often rounded) juxtapleural opacification (Hampton hump) without air bronchograms
consolidation with internal air lucencies, "bubbly consolidation"; this represent non-infarcted aerated lung parenchyma co-existing side-by-side with infarcted lung in the same lobule
- sometimes scattered areas of low attenuation within the lesion (necrosis) and sometimes enhancement of the perimeter of the infarct
- cavitation: may seen in septic embolism and in infection of a bland infarct (cavitatory pulmonary infarction)

CT scans are useful for detecting structural and focal abnormalities (such as infarcts/hypodense areas, hemorrhage, tumors, cerebral calcification, abscess, and basilar meningitis) [38]. Brain atrophy has been noted in some patients; this finding has been thought by some (but disputed by others) to reflect the effects of steroid therapy [6] or age [4]. We have seen brain atrophy out of proportion to a patient's age, and prior to steroid therapy.
