Cardiac tamponade as the initial manifestation of primary pericardial mesothelioma

Although cardiac tamponade is a known complication of malignancy, it is rarely the initial manifestation. We report a 46-year-old male who presented with malignant cardiac tamponade 6 months prior to the definitive diagnosis of primary pericardial mesothelioma. A thorough literature search has not revealed a similar care.
