Keywords: Pulmonary eosinophilia; Allergic bronchopulmonary aspergillosis; Pneumonia, eosinophilic; Computed tomography. 1. Introduction. The pulmonary eosinophilias are a diverse group of disorders characterised by pulmonary infiltrates which are rich in eosinophils. There is usually, but not invariably, an associated
16 Sep 2008 Abstract. Pulmonary eosinophilia comprises a heterogeneous group of diseases defined by eosinophilia in pulmonary infiltrates (bronchoalveolar lavage fluid) or in tissue (lung biopsy specimens). Although the inflammatory infiltrate is composed of macrophages, lymphocytes, neutrophils and eosinophils,
pulmonary infiltration with eosinophilia (PIE) syndromes. Common interstitial lung diseases with increased eosinophils and parenchymal infiltration include bacterial, fungal, and parasitic infections, allergy to certain fungi, diffuse connective tissue diseases, vasculitides, various drug-induced syndromes, cancer,.
A seven-month-old collie and a four-year-old. Jack Russell terrier were presented with coughing and dyspnoea of varying duration. A peripheral and pulmonary eosinophilia was detected in both dogs. After ruling out heartworm disease, lungworms, fungal pneumonia and drug reac- tions, a diagnosis of pulmonary infiltrates

vary from an acute eosinophilic alveolitis to histiocytic infiltration depending on the stage of the disease. While earlier studies had suggested that the disease runs a benign course, more recent work has shown that untreated TPE could result in a fair degree of respiratory morbidity. Pulmonary function tests may show a
Infiltration of the pulmonary parenchyma may be seen in the thoracic roentgenogram in a variety of diseases. Such infiltration may be asso- ciated with eosinophilia of the peripheral blood, and when this associa- tion occurs, the descriptive term "pulmonary infiltration with eosino- philia" (P.LE. syndrome) is used. It is seen in
The eosinophilic lung diseases are a heteroge- neous group of pulmonary disorders charac- terized by an increase in circulating and tissue eosinophils. Pulmonary eosinophilia can be defined generally as pulmonary infiltrates on radi- ological imaging together with an increase in the absolute number of eosinophils
CLASSIFICATION OF CASES OF PULMONARY EOSINOPHILIA. The definition of pulmonary eosinophilia as " pulmonary infiltration with blood eosinophilia" covers a very wide range of diseases, varying from the mild and transient changes in true Loffler's syndrome to the severeand often fatal mani- festations of polyarteritis
fluid eosinophilia. (a) Thin-section (1-mm collimation) CT scan (lung windowing) shows ground-glass opacities with intralobular interstitial thickening in both lower lobes. (b) High-power photomicrograph (original magnifica- tion, 400; H-E stain) of a transbronchial lung biopsy specimen shows infiltration of eosinophils and
