Hypothyroidism presenting with recurrent pericardial tamponade.

We present a case of pericardial tamponade caused by hypothyroidism. A 66-year-old man presented with acute chest pain radiating to the back. Computed tomography ruled out an aortic dissection but revealed a large pericardial effusion, which was confirmed on transthoracic echocardiography showing features of tamponade.
