A 32-year-old man presented with palpitations and central chest pain, examination was unremarkable and chest radiograph was normal. ECG demonstrated right axis deviation and inferolateral T-wave inversion; cardiac enzymes were normal. Cardiac MRI demonstrated multifocal, patchy subepicardial and mesocardial left ventricular late gadolinium enhancement, suggestive of cardiac sarcoidosis. Whole body and dedicated cardiac fluorodeoxyglucose (FDG)-positron emission tomography (PET) was performed 60 min after radiotracer injection following a special patient preparation to suppress physiological myocardial uptake of glucose. This consists of a high-fat, low-carbohydrate diet the day before scanning followed by a 15 hours fast. The PET revealed multifocal metabolically active cardiac inflammation, corresponding to the areas of late gadolinium enhancement on MRI and extensive sites …
