Diffuse FDG uptake of the bilateral atrial walls in a patient with atrial fibrillation.
A 59-year-old man, who had a 3-year history of paroxysmal atrial fibrillation, was referred to our hospital because of palpitation for 12 hours. Atrial fibrillation was confirmed by ECG. F-FDG PET/CT scan was performed showing diffuse FDG uptake of the bilateral atrial walls. Enhanced chest CT showed that the bilateral atria and ventricles were normal. This case highlights that atrial fibrillation should be included in the differential diagnosis of abnormal atrial FDG accumulation along with tumor and inflammatory processes.
