Low voltage ECG, T wave flattening and T wave inversion are ECG abnormalities usually seen in pericardial effusion and revert to normal after initiation of hormone replacement therapy before biochemical correction of hypothyroidism2.

LEURO-PERICARDIAL EFFUSION AS SOLE PRESENTATION OF HYPOTHYROIDISM

This was evidenced in this bird, where atherosclerosis is one of several suspected causes that may have led to the bird being in congestive heart failure, and pericardial effusion is suspected to have been an effect of the heart failure.

What Is Your Diagnosis?

Perhaps, the most dramatic case report was a 20-year-old female with recent diagnosis of lupus (with active myositis treated with oral prednisone and azathioprine) who presented with acute myocarditis as evidenced by an ejection fraction of 15% and large pericardial effusion. Left and right cardiac catheterization was unremarkable, but she required intraaortic balloon pump and soon developed cardiogenic shock.

Viral etiology of this condition is possible but unlikely because usually foetal viral myocarditis causes global cardiomegaly, heart failure, or arrhythmias and massive pericardial effusion. As already reported by Blondheim et al.
