Identify the most important abnor-malities indicative of hypersensitiv-ity pneumonitis at chest radiography and CT. 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.

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. Awareness of the various manifestations of HP is important for early diagnosis and management.

The high-resolution CT and pathologic features of chronic HP frequently overlap with those of nonspecific interstitial pneumonia and usual interstitial pneumonia. Awareness of the various manifestations of HP is important for early diagnosis and management. In the sections that follow, the clinical, pathologic, and radiologic aspects of hypersensitivity pneumonitis are described on the basis of a thorough review of the published English-language literature as well as chest radiographs and computed tomographic (CT) scans compiled by the authors over the past 30 years.

Diagnosis: Subacute Hypersensitivity Pneumonitis (bird fancier's lung) - Images, diagnosis, treatment options, review - Thoracic Imaging Case.

PRESENTED IN RADIOLOGICAL-PATHOLOGICAL CONFERENCE 14 JULY 2015 BY T.CHAYOVAN Hypersensitivity Pneumonitis: Essential Radiologic and Pathologic Findings Teri J. Franks, MD, Jeffrey R. 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).

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). Context: - Chronic hypersensitivity pneumonitis (CHP) has emerged from obscurity during the past 15 years and is now recognized as a very common form of fibrosing interstitial pneumonia but one that is frequently misdiagnosed both clinically and on surgical lung biopsy as usual interstitial pneumonia/idiopathic pulmonary fibrosis (UIP/IPF) or fibrotic nonspecific interstitial pneumonia.

Miliary TB: random nodules of the same size. Subacute hypersensitivity pneumonitis (HP) with organizing pneumonia. Patchy peribronchovascular consolidation is present in a patient with HP, typical of organizing pneumonia. While organizing pneumonia is commonly seen pathologically in patients with HP, it is only rarely seen as the predominant abnormality on HRCT. Hypersensitivity Pneumonitis, Acute-Subcute Jud W.
