Resumo

As alterações pleurais e pulmonares decorrentes da exposição ao asbesto podem ser benignas, como o derrame e as placas pleurais, ou malignas, como o carcinoma de pulmão e o mesotelioma pleural. O derrame pleural é a manifestação mais comum nos primeiros anos após a exposição e os aspectos de imagem são incaracterísticos. O espessamento pleural difuso compromete a pleura visceral, não sendo específico da exposição ao asbesto. As placas pleurais, espessamentos focais da pleura, são consideradas marcadores de exposição. A asbestose corresponde à fibrose do parênquima pulmonar pelo asbesto, predominando nos lobos inferiores, e a atelectasia redonda a um colapso pulmonar periférico, geralmente associado a alterações pleurais. O carcinoma pulmonar e o mesotelioma pleural são mais prevalentes em indivíduos expostos. O objectivo deste estudo é ilustrar as principais alterações de imagem das alterações relacionadas com o asbesto.

Abstract

Pleural and pulmonary asbestos-related diseases range from benign conditions, like pleural effusion and pleural plaques, to some neoplasias, such as lung cancer and malignant mesothelioma. Pleural effusion is the earliest finding after asbestos exposure, but the imaging findings are not specific. Diffuse pleural thickening involves the visceral pleura and pleural plaques are considered to be hallmarks of exposure. Asbestosis is the pulmonary fibrosis due to asbestos. Rounded atelectasis is a peripheral lung collapse in these individuals, generally related to pleural disease. Some neoplasias, like lung carcinoma and pleural mesothelioma, are more prevalent in asbestos-exposed subjects. The aim of this essay is to illustrate the main imaging findings of asbestos-related diseases.
