ABSTRACT
Mesothelioma epidemic in asbestos consuming countries is anticipated within 30 years. Recognition of the malignant disease is inevitable to prevent advanced cases to be found after it is too late to be cured. We aimed to depict radiographical findings of benign pleural abnormalities and the findings to suspect malignant mesothelioma. The ILO 2000 classification of radiographs of pneumoconioses (ILO2000), a widely used classification for medical screening of pneumoconioses, was revised to make systematic decision on the types of pleural thickening: plaque and diffuse pleural thickening. The costophrenic angle obliteration is taken as prerequisite to diffuse pleural thickening, that is usually formed after benign pleural effusion. Existence of advanced pleural thickening makes it difficult to detect other abnormal findings, including malignancy on radiographs. In this presentation, some cases with malignant complication are shown to depict differences between benign pleural diseases and malignant mesothelioma. It is needed to accumulate the benign and malignant cases related to asbestos among Asian countries in order to standardize the medical screening system in this region. In the present study, some cases with mesothelioma or benign pleuritis on chest X-ray are presented.
