caption_attribution_description: Interstitial multinucleate giant cells. Scattered individual or small groups of giant cells are a common finding in hypersensitivity pneumonitis and may far outnumber granulomas in some cases.
context_page_description: Pneumonitis describes general inflammation of lung tissue. Possible causative agents include radiation therapy of the chest, exposure to medications used during chemo-therapy, the inhalation of debris, aspiration, herbicides or fluorocarbons and some systemic diseases. If unresolved, continued inflammation can result in irreparable damage such as pulmonary fibrosis.
  Pneumonitis is distinguished from pneumonia on the basis of causation as well as its manifestation. Pneumonia can be described as pneumonitis combined with consolidation and exudation of lung tissue due to infection with microorganism. The distinction between Pneumonia and Pneumonitis can be further understood with Pneumonitis being the encapsulation of all respiratory infections, and pneumonia as a localized infection. For most infections, the immune response of the body is enough to control and apprehend the infection within a couple days, but if the tissue and the cells can't fight off the infection, the creation of pus will begin to form in the lungs which then hardens into lung abscess or suppurative pneumonitis.
