Background: This guideline addresses the diagnosis of hypersensitivity pneumonitis (HP). It represents a collaborative effort among the American Thoracic Society, Japanese Respiratory Society, and Asociación Latinoamericana del Tórax.

Acute hypersensitivity pneumonitis on chest radiography. Anteroposterior chest radiograph shows extensive bilateral hazy areas of increased opacity (ground-glass opacities) and patchy areas of consolidation. The diagnosis of acute hypersensitivity pneumonitis (bird fancier’s lung) was based on the clinical findings and history of exposure. Hypersensitivity pneumonitis is a diffuse, granulomatous interstitial lung disease caused by repeated exposure to a wide spectrum of environmental antigens. Subacute hypersensitivity pneumonitis usually results from intermittent or continuous exposure to low doses of antigen and is histologically characterized by the presence of cellular bronchiolitis, non-caseating granulomas, and bronchiolocentric interstitial pneumonitis with a predominance of lymphocytes. Chest radiographs obtained in many patients with hypersensitivity pneumonitis are normal (47). Abnormal radiographic findings observed in some patients include numerous poorly defined small (less than 5-mm) opacities throughout both lungs, sometimes with sparing of the apices and bases.

Acute hypersensitivity pneumonitis is histologically characterized by the presence of neutrophilic infiltration of the respiratory bronchioles and alveoli. A pattern of diffuse alveolar damage and temporally uniform, non-specific, chronic interstitial pneumonitis may also be seen. 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. Background: 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. Acute hypersensitivity pneumonitis on chest radiography.

Galvin, MD Surgical Pathology Clinics Volume 3, Issue 1, Pages 187-198 (March 2010) DOI: 10.1016/j.path.2010.03.005 Purpose: Radiologic diagnosis of chronic hypersensitivity pneumonitis (CHP) presenting a usual interstitial pneumonia (UIP) pattern is challenging. The aim of this study was to identify the high-resolution CT (HRCT) findings which are useful to discriminate CHP-UIP from idiopathic pulmonary fibrosis (IPF).

Abbreviations: BAL = bronchoalveolar lavage, IPF = idiopathic pulmonary fibrosis, NSIP = nonspecific interstitial pneumonia, UIP = usual inter-stitial pneumonia Hypersensitivity pneumonitis (HP) is a diffuse granulomatous interstitial lung disease caused by inhalation of various antigenic organic particles [].HP is often difficult to diagnose because the clinical manifestations are nonspecific and the radiologic and histologic patterns can mimic those of other interstitial and small airway diseases []. Hypersensitivity pneumonitis (HP) is an allergic lung disease caused by the inhalation of antigens contained in a variety of organic dusts. 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.

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. Several diseases can cause BAL lymphocytosis —including sarcoidosis, infections, rheumatologic disorders, inflammatory bowel disease, radiation pneumonitis, drug-induced pulmonary reactions, cryptogenic organizing pneumonia, and NSIP—but in the appropriate clinical setting this finding is strongly suggestive of hypersensitivity pneumonitis.
