Hypersensitivity pneumonitis  Diffuse granulomatous interstitial lung disease  Caused by an immunologic response to repeated aerosol inhalation  Clinical, radiologic, and histologic findings are quite variable  Diagnosis depends on a constellation of findings rather than a single defining feature 3. Hypersensitivity pneumonitis (HP), also known as extrinsic allergic alveolitis, is an immune mediated lung disease occurring in response to repeated inhalation of an antigen. 1–6 It appears to be an underdiagnosed condition, often masquerading as a recurrent pneumonia, idiopathic pulmonary fibrosis, Hamman-Rich disease, or interstitial pneumonia. 2018-09-19 1996-04-01 Background Hypersensitivity pneumonitis (HP) is caused by exaggerated immune response, either in the form of immune-complex hypersensitivity (acute HP) or Th2 immune response (subacute, chronic HP), to inhalation of different organic antigens: fungi, yeasts, mycobacteria, bacteria, … 2017-06-16 Hypersensitivity pneumonia (HP), also called exogenous allergic alveolitis, is a chronic interstitial pneumonia induced by a hypersensitivity reaction to an identified or unidentified antigen in exposed and susceptible individuals that may progress to terminal lung fibrosis. The diagnosis of HP presents a diagnostic challenge.

The radiologic findings include diffuse ground-glass opacification, centrilobular ground-glass opacities, air trapping, fibrosis, lung cysts, and emphysema. The histologic and radiologic features in some cases may resemble those of usual interstitial pneumonia or nonspecific interstitial pneumonia. Hypersensitivity pneumonitis (HP) is an interstitial lung disease with a better prognosis, on average, than idiopathic pulmonary fibrosis (IPF). We compare survival time and pulmonary function trajectory in patients with HP and IPF by radiologic phenotype.

Awareness of the various manifestations of HP is important for early diagnosis and management. Se hela listan på radiopaedia.org Areas of organizing pneumonia may also be seen. In some cases, antigenic material is visible, or organisms may grow on culture. As in the acute and subacute forms, lymphocytic peribronchiolar inflammation is also seen in chronic hypersensitivity pneumonitis, but with plasma cell predominance.

Farmer's lung is the best-known HP syndrome and results from the inhalation of fungal organisms that grow in moist hay or exposure to birds as pets (1). Chronic Hypersensitivity Pneumonitis. An important differentiating feature of hypersensitivity pneumonitis is the presence of air trapping, which is the primary reason to perform expiratory imaging as part of the CT examination. 6 On the expiratory RV image, we see areas of air trapping, suggesting HP. Areas of organizing pneumonia also may be seen. The high-resolution CT and pathologic features of chronic HP frequently overlap with those of nonspecific interstitial pneumonia and usual interstitial pneumonia.
