“…Similar to what is seen in COP, consolidations can be migratory. In fact, the two diseases can be difficult or impossible to distinguish on HRCT scans, (106) in some cases also overlapping in lung biopsies. The diagnosis of CEP is based on a history of insidious clinical onset, characteristic chest X-ray appearance of peripheral infiltrates with transient opacities, and peripheral eosinophilia.…”

High-resolution computed tomography (HRCT) is the radiological imaging technique best suited to revealing changes in lung structure. Various HRCT findings, taken together, can represent typical patterns. These patterns, in conjunction with the anatomical distribution of findings and with clinical data, can narrow the differential diagnosis of diffuse interstitial lung disease and, in many cases, indicate the correct diagnosis with a high degree of accuracy. The most common HRCT patterns seen in cases of diffuse interstitial lung diseases are the nodular pattern, linear/reticular opacities, cystic lesions, ground-glass opacities and consolidations. This article reviews the correlations between HRCT patterns and pathologic findings, summarizing the most common causes, as well as detailing the methods of investigation employed in order to diagnose the most common types of chronic diffuse lung disease.Keywords: Lung diseases, interstitial/pathology; Tomography, X-Ray computed; Diagnostic techniques, respiratory system. ResumoA tomografia de alta resolução (TCAR) é a técnica de imagem radiológica que reflete mais de perto as alterações da estrutura pulmonar. Os vários achados tomográficos podem ser combinados para formar padrões típicos. Estes, conjuntamente com a distribuição anatômica dos achados, e com os dados clínicos, podem estreitar o diagnóstico das doenças intersticiais pulmonares difusas, e em vários casos sugerir o diagnóstico correto com alto grau de acurácia. Os padrões mais comuns das doenças intersticiais pulmonares difusas na TCAR são o nodular, linear e reticular, lesões císticas, opacidades em vidro fosco e consolidações. Este artigo revisa as correlações entre os padrões tomográficos na TCAR e os achados patológicos e resume as causas mais comuns e os métodos de investigação para se atingir um diagnóstico nas doenças pulmonares crônicas difusas mais comuns.Descritores: Doenças pulmonares intersticiais/patologia; Tomografia computadorizada por raios X; Técnicas de diagnóstico do sistema respiratório.* Study carried out in the

“…The CT findings in AEP patients consisted mainly of bilateral patchy areas of ground-glass attenuation, interlobular septal thickening, thickening of the bronchovascular bundles, and the presence of pleural effusion without cardiomegaly (Cheon et al, 1996). Unlike AEP, bilateral air-space consolidation with peripheral predominance was the most frequent CT finding in CEP, followed by linear and reticular opacities and ground-glass opacities (Mayo et al, 1989;Arakawa et al, 2001). HRCT manifestations of drug-induced EPs resemble those of chronic EP, bilateral air-space consolidation, peripherally distributed ground-glass opacities, nodules, and irregular lines (Souza et al, 2006).…”

ABSTRACT. The diagnosis of eosinophilic pneumonia (EP) is rare and challenging. This condition is frequently misdiagnosed as pulmonary tuberculosis, lymphoma, schistosomiasis, Wegener's granuloma, severe acute respiratory syndrome, or severe communityacquired pneumonia. Herein, we report a case in which computed tomography (CT)-guided percutaneous lung biopsy was used to diagnose EP without alveolar eosinophilia or peripheral eosinophilia. A roundworm identified in the patient's stool confirmed the precise diagnosis to be parasitic EP. This is, to our knowledge, the first reported case of EP confirmed by CT-guided percutaneous lung biopsy. CT-guided percutaneous lung biopsy may represent a new tool for the diagnosis of EP in patients without typical alveolar eosinophilia or peripheral eosinophilia.

“…Diseases with the symptoms of allusive signs of the chronic eosinophilic pneumonia were selected for comparison [26][27][28]. The first group was composed of 50 accidentally selected consecutive patients with radiographically confirmed hospital treated community-acquired pneumonia (COP); the second group consisted of 21 consecutive asthmatic patients with previously diagnosed disease, who had caught hospital treated COP between 1997 and 2008.…”

AbstractChronic eosinophilic pneumonia is a rare interstitial lung disorder, which causes diagnostic difficulties. Often the disease is diagnosed correctly after several weeks or months following initial presentation. The aim of the study was to prospectively evaluate peculiarities of manifestation of idiopathic chronic eosinophilic pneumonia (ICEP), which may allow to improving early diagnosis. Twenty patients with ICEP were involved in this investigation. The cases of acute eosinophilic pneumonia and cases of chronic eosinophilic pneumonia of known origin were excluded. To define archetypal signs of the idiopathic chronic eosinophilic pneumonia, 3 comparable groups were selected. They were the group of 50 patients with community-acquired pneumonia (COP); the group of 21 asthmatic patients with COP, and the cluster of 10 patients with morphologically confirmed cryptogenic organizing pneumonia (OP). Clinical and radiological manifestation of ICEP was similar to COP and cryptogenic OP manifestation. We have found that chest pain; fine rales and pleurisy were unrepresentative for ICEP. However, blood eosinophilia was typical sign of ICEP and wheezing was a frequent observation. Usually ICEP patients had relative mild clinical symptoms and moderate increased C reactive protein (CRP) level even in cases of multiple pulmonary infiltrates. In conclusion, in cases of not typical pneumonia course, i.e. non-resolving or recurrent pulmonary infiltrates; relative mild clinical symptoms and moderate increased CRP level with multiple pulmonary infiltrates; blood eosinophilia and/or signs of airway obstruction eosinophilic pneumonia should be suspected and bronchoalveolar lavage and/or bronchoscopic lung biopsy performed.

Bronchiolitis Obliterans with Organizing Pneumonia Versus Chronic Eosinophilic Pneumonia

Abstract: Although several of the high-resolution CT findings of BOOP and CEP are different, these diseases are differentiated with confidence in only a small percentage of cases.
