HP comes from an immune-mediated inflammatory process involving the lung parenchyma (terminal bronchioles, alveoli, and interstitium), based on mechanisms likely independent from single causative agent, mediated by immune complexes in the acute phases of the disease and an altered response of T lymphocytes in the early stages subacute and chronic (Vogelmeier et al. 1993; Barrera et al. 2008). The lung parenchyma is that portion of the lungs involved in gas exchange. The most prominent structure in this region is the alveolus (Figure 1).Each alveolus in the lung parenchyma opens directly into an alveolar duct or occasionally, in a limited number of species, into a respiratory bronchiole. Organizing pneumonia is a common reaction pattern of the lung parenchyma to different pathologic conditions, such as infections or tumors as well as the most diverse physical and chemical stimuli.

Malignancy: Malignancy is uncontrolled cell growth of tissue in the lungs … Anatomy and Physiology of the Lungs Bronchi gradually form more generations, like a tree branch, and become smaller and smaller. The lung parenchyma is used to describe the respiratory bronchioles (smallest bronchi) and alveoli, where carbon dioxide and oxygen are exchanged. Lung ultrasound requires identification of the relevant anatomy. With the transducer held longitudinally, with the indicator cephalad, that includes the superior and inferior rib (seen as hyperechoic lines with dense shadows) and the pleura (a bright hyperechoic line just deep to the ribs).
