Key result
Atrial fibrillation can cause diffuse FDG uptake of the bilateral atrial walls on F-FDG PET/CT, which should be considered in the differential diagnosis alongside tumor and inflammatory processes.

AF should be considered in the differential for diffuse atrial FDG uptake on PET/CT; case report leaves open prevalence and need for prospective validation.
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.

Dong et al. (2013) conducted a case report in Atrial Fibrillation (n=1). F-FDG PET/CT scan was evaluated on FDG uptake of the bilateral atrial walls. Atrial fibrillation can cause diffuse FDG uptake of the bilateral atrial walls on F-FDG PET/CT, which should be considered in the differential diagnosis alongside tumor and inflammatory processes.
