Recurrent cardiac tamponade in a young woman.

A young woman presented with recurrent pericardial effusion, she had previously been treated with antitubercular medications. She had clinical features of systemic sclerosis (SSc) which was subsequently confirmed on further workup. She was also found to be profoundly hypothyroid. Cardiac tamponade is uncommon in both SSc as well as hypothyroidism, unlike in our patient who was found to have both of these disorders. In her case, the pericardial involvement probably ante-dated the other features of SSc.
