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. Developed by renowned radiologists in each specialty, STATdx provides comprehensive decision support you can rely on - Hypersensitivity Pneumonitis 2016-06-15 The radiological appearances of hypersensitivity pneumonitis with an explanation of air trapping 🎁 Watch Series #1 of Radiology Masters LIVE replays on demand Radiology Masters Learn faster 2020-02-26 PubMed Purpose: To retrospectively compare in patients with chronic hypersensitivity pneumonitis (HP) the computed tomographic (CT) imaging features suggestive of fibrosis with pathologic evidence of fibrosis at surgical lung biopsy and to compare a usual interstitial pneumonia (UIP) pattern at CT with survival. Materials and methods: Institutional review board approval and informed consent were Spectrum of Findings with Chronic Hypersensitivity Pneumonitis.

The clinical, radiological, and pathological features of chronic hypersensitivity pneumonitis have recently been described. This study reviews the previously Se hela listan på radiopaedia.org Acute hypersensitivity pneumonitis, also known as acute extrinsic allergic alveolitis, refers to the episodic form of this condition usually happening in just a few hours after the antigen exposure and often recurring with the re-exposure. Chronic hypersensitivity pneumonitis (CHP) refers to hypersensitivity pneumonitis where there is radiological evidence of fibrosis and represents the end-stage of repeated or persistent pneumonitis 7.

As in the acute and subacute forms, lymphocytic peribronchiolar inflammation is also seen in chronic hypersensitivity pneumonitis, but with plasma cell predominance. Usual Interstitial Pneumonia (UIP): basal and peripheral fibrosis, honeycombing.
