Brown adipose activation and reversible beige coloration in adipose tissue with multiple accumulations of 18 F‐fluorodeoxyglucose in sporadic paraganglioma: A case report

In pheochromocytoma/paraganglioma, nontumorous high 18F‐fluorodeoxyglucose accumulations are observed in both beige and brown adipose tissues. Recognizing this feature of 18F‐fluorodeoxyglucose accumulation can help physicians make precise diagnoses and help them avoid the pitfalls of a false‐positive 18F‐fluorodeoxyglucose positron emission tomography result, preventing unnecessary interventions.
