Pericardial Effusion with Cardiac Tamponade as a form of presentation of Primary Hypothyroidism.

Hypothyroidism is a rare cause of pericardial effusion (PE). Pericardial effusion secondary to hypothyroidism remains a diagnostic challenge for clinicians because of its inconsistency between symptoms and amount of pericardial effusion. We report an atypical case that presented with ascites and was diagnosed to have cardiac tamponade secondary to primary hypothyroidism. Besides repeated pericardiocentesis she eventually required surgical management and optimization of medical therapy to manage the massive pericardial effusion.
