Malignant pleural mesothelioma forming a huge mediastinal mass and causing atrial fibrillation. Indian Journal of Pathology & Microbiology. 2012 Oct-Dec 55(4): 513-515.http://imsear.searo.who.int/handle/123456789/145648A patient with malignant pleural mesothelioma was admitted with atrial fibrillation. Chest computed tomography showed a huge mediastinal tumor adjacent to the heart. Autopsy revealed a 12 × 9.5 -cm mediastinal mass involving the right lung, which distorted and stretched the myocardial sleeve surrounding the right inferior pulmonary vein. This case demonstrates that advanced malignant pleural mesothelioma can cause atrial fibrillation, possibly by stimulating myocardium around a pulmonary vein.enAtrial fibrillationmesotheliomapleuraAgedAtrial Fibrillation --epidemiologyAtrial Fibrillation --etiologyHumansMaleMediastinal Neoplasms --epidemiologyMediastinal Neoplasms --etiologyMesothelioma --complicationsMesothelioma --epidemiologyPleural Neoplasms --complicationsPleural Neoplasms --epidemiologyArticle
