Although there tends to be some scarring with time because of superimposed infections, the emphysematous process is one of loss of lung parenchyma, not fibrosis. There are two major types of emphysema: centrilobular (centriacinar) and panlobular (panacinar). The former involves primarily the ...
59 The initial pulmonary focus of infection (Ghon focus) subsequently heals by fibrosis and may show dystrophic calcification. This Ghon focus together with the accompanying calcified site of infection in a hilar lymph node are termed the Ranke complex, (Fig. 8.54) and the foci of primary ...
False-positive pulmonary angiograms may result from mediastinal disorders such as radiation fibrosis and tumors. CT angiography is an accurate, noninvasive tool in the diagnosis of PE at the main, lobar, and segmental pulmonary artery levels. A major advantage of CT angiography over standard ...
Idiopathic pulmonary fibrosis is a progressive fibrotic disease of unknown etiology characterized by imaging and histologic features of usual interstitial pneumonia (UIP). The term IPF is used in the absence of secondary causes of UI...
Conclusions: Idiopathic tracheal stenosis, also termed idiopathic laryngotracheal stenosis, has distinctive pathology, both in terms of the character of the fibrosis and in terms of ductular dilatation and periductal fibrosis, which has some aspects are reminiscent of bronchiolitis as can be seen in ...

It is important to sample less-affected lung tissue that has not gone onto end-stage honeycomb lung, as end-stage pulmonary fibrosis is generally not diagnostically specific and may not facilitate identification of the underlying interstitial pathology. All lung lobes should be sampled for ...
The airways of patients with cystic fibrosis (CF) are highly complex, subject to various environmental conditions as well as a distinct microbiota. Pseudomonas aeruginosa is recognized as one of the most important pulmonary pathogens and the predominant
