A 59-year-old man was admitted with a cerebral infarction. He showed atrial fibrillation, signs of heart failure and severe hypertension. The electrocardiogram showed atrial flutter with a fast ventricular rate. His echocardiogram showed a poor contracting left ventricle. During the follow-up, his blood pressure and cardiac function normalised and the rhythm returned to sinus rhythm. The coronary angiogram appeared normal. In 2013, an abdominal echo and computed tomography (CT) scan were performed because of abdominal complaints. This revealed a mass close to the right kidney (Fig. 1). The I-123 MIGB SPECT (Also known as Iodium 113-metaiodobenzylguanidineSPECT)scan showed pathological stacking of I-123 (Fig. 2). The diagnosis phaeochromocytoma was made. The tumour was surgically removed. Pathological examination revealed a benign phaeochromocytomas. DNA testing in the Clinical Genetics Department excluded hereditary causes. Phaeochromocytomas are frequently discovered by chance during a radiological examination [1]. Next to CT and magnetic resonance imaging, molecular imaging should be considered for analysis [2, 3].
