“…Patchy, homogeneous, nonsegmental infiltrates appear and disappear in unpredictable fashion and have a tendency to recur in the same loca tions [11,20]. A characteristic picture is one of dense peripheral infil trates often involving the entire 'cortex' of the lung leaving but a center of perihilar aeration.…”

An association betwen migratory pulmonary infiltrates and peripheral eosinophilia has been known for at least 40 years. Diagnostic challenges still exist in the classifications within this syndrome. We describe a 33-year-old female without asthma but with definite ‘atopy’ who had a 4-year history of recurring pulmonary lesions. These were sometimes segmental, at other times dense and peripheral, and once there was lobar atelectasis due to mucoid impaction. Diagnosis by lung biopsy revealed eosinophilic pneumonia with bronchiolitis obliterans as a prominent feature. Steroid treatment resulted in prompt improvement; during a 5-year follow-up the infiltrates have not recurred but there has been persistent mild obstruction.

“…The term eosinophilia denotes an absolute eosinophil count above 500 cells/microliter (8). In simple pulmonary eosinophilia, the degree of eosinophilia varies, ranging between 1,000 and 50,000 cells/microliter (10), but does not appear to correlate with the amount, duration, or intensity of pulmonary infiltration (11,12). Symptoms are usually lacking and physical findings are often absent (11).…”

“…Neither cavitation in consolidation nor findings of pleural effusion, lymph node enlargement, or cardiomegaly have been reported (1). Hennell et al (12) described the radiographic findings of five patients with transient eosinophilic lung infiltration as confluent and patchy in appearance which may be radiating from the hilum, and often symmetric in two lungs. In fact, a patient with probable hypereosinophilic syndrome was included in his study and three patients were asthmatics.…”

“…About one half of the patients in whom simple pulmonary eosinophilia was initially diagnosed will eventually be shown to be affected by infestation, drug reaction, or environmental exposure (1,2,5). The etiology is quite obscure; the evidence to date suggests that an allergy is involved (3,4,6,10,12). In light of the above, the possibility of parasitic infestation, drug reaction, environmental exposure, and underlying malignancy should be carefully investigated (2).…”

Purpose :The purpose of our study is to describe the chest radiographic and CT findings of simple pulmonary eosinophilia. Materials and Methods : Twenty-six patients with simple pulmonary eosinophilia und e r went chest radiography and CT scanning; the results were analyzed retrospectively by two chest radiologists, focusing on the patterns and distribution of the parenchymal abnormalities. Results :The chest radiographs were normal in eight patients (31 %), while among the remaining 18 patients, they showed subtle opacity (n=9), nodules (n=8), consolidation (n=2), and mass (n=1). Fo l l ow-up chest radiographs (n=18) demonstrated complete (n=16) or partial (n=1) resolution of parenchymal lesions or migratory lesions (n=1). On CT, nodule(s) (n=19) were most commonly seen, followed by ground-glass opacity (n=16), consolidation (n=3), and mass (n=1). A peripheral halo surrounding a nodule or an area of consolidation was seen in 18 patients. The nodules(s) (n=19) were subpleural (n=13) or random (n=6). Areas of ground-glass opacity (n=16) we r e subpleural (n=13), random (n=2), or central (n=1). All lesions were patchy rather than diffuse. Fo l l ow-up CT in nine patients showed complete (n=7) or partial (n=2) resolution of parenchymal lesions. Conclusion : Chest radiographs of patients with simple pulmonary eosinophilia often r eveal no abnormality. The most common finding is subtle opacity or nodule(s), while CT reveals transient nodule(s) with a surrounding halo or transient areas of groundglass opacity.
