An 84-year-old man was referred for the evaluation of a suspected gastrointestinal neoplasia. 18F-FDG PET/CT scan was performed showing, in addition to the physiological myocardial FDG uptake in the left ventricular wall, an unusual diffuse FDG uptake of the bilateral atrial walls. During his visit to the nuclear medicine unit, the patient became unwell, and an ECG was performed, suggestive of an atrioventricular nodal re-entrant tachycardia. Our case highlights the importance of including supraventricular arrhythmia such as atrioventricular nodal re-entrant tachycardia in the differential diagnosis of atrial FDG uptake.
