title: Hypermetabolic mesenteric brown adipose tissue on dual-time point FDG PET/CT in a patient with benign retroperitoneal pheochromocytoma.
abstract: Intense FDG uptake of the mesenteric brown adipose tissue (BAT) is rare. We present a case of benign retroperitoneal pheochromocytoma showing multiple hypermetabolic regions corresponding with common locations of BAT. Furthermore, the mesenteric region showed intense FDG uptake, with SUVmax of 10.6. FDG PET/CT findings of this case supports the previous theories that the incidence of BAT may be higher in patients with pheochromocytoma than in patients without, and the intra-abdominal fat of human adults, including the omental fat, which is brown adipose tissue in infancy, becomes reactivated in the presence of high circulating noradrenaline concentrations.
