A "Vanishing", Tuberculous, Pericardial Effusion.

We present an iatrogenic, pleuro-pericardial connection resulting from pericardiocentesis of a large, tuberculous, pericardial effusion. Recognition of this situation is paramount when one is unable to aspirate pericardial fluid after a successful, initial puncture. Such knowledge will help prevent myocardial or coronary artery injury with further attempts at aspiration.
