A rare case of primary malignant pericardial mesothelioma.

Primary malignant pericardial mesothelioma (PMPM) is a rare tumor of the pericardium. The cause of this tumor is unknown and it has a very poor prognosis. Exposure to asbestos is correlated with the onset of pleural and peritoneal mesothelioma; however, the role of asbestos in pericardial mesothelioma is unclear. Here we highlight the radiological features of this rare tumor and its correlative pathological confirmation with the help of new immunohistochemical (IHC) markers.
