In addition, other types of lung disease like nodules and cavities in the lung parenchyma are frequently associated with pulmonary artery involvement, … are primarily distributed in the lung tissue along lymphatics. For example, air containing bronchi in mass like lesions Ferraro P, Trastek VF, Adlakha H et-al. Restrictive lung diseases are characterized by reduced lung volume, either because of an alteration in lung parenchyma or because of a disease of the pleura, chest wall, or neuromuscular apparatus. addition, other types of lung disease like nodules and cavities in the lung parenchyma are frequently associated with pulmonary artery involvement, and can be misinterpreted as being due to infection. There are certain radiologic features, however, that are J. Clin. Scans were assigned a quantitative degree of involvement based on previously described CT findings. Although several reports have described the effects of different drugs … Patchy abnormal increased density of the lung with preserved visibility of The involvement of the lung parenchyma by sarcoidosis can have very different appearances ranging from reticulonodular lung tissue densities to multiple masses and miliary lesions.
