A Patient with Cardiac Sarcoidosis in Whom an Abnormal Myocardial Uptake of Fluorine-18 Fluorodeoxyglucose and Sustained Ventricular Tachycardia Recurred 3.5 Years after Discontinuing Oral Corticosteroid Therapy.

We herein report a woman diagnosed with cardiac sarcoidosis (CS) based on the presence of epithelioid granulomas in non-cardiac organs and clinical findings including sustained ventricular tachycardia (VT) and cardiac dysfunction. She stopped oral corticosteroid after 4 years of treatment, and an abnormal myocardial uptake of fluorine-18 fluorodeoxyglucose and sustained VT recurred 3.5 years later. There is no consensus concerning whether or not corticosteroid therapy should be discontinued in the treatment of CS. As a relapse of sarcoidosis-related inflammation may be associated with life-threatening arrhythmia, some patients should continue corticosteroid therapy, even at low doses.
