Bilateral adrenal masses were found by ultrasound on a 55-year-old man with sudden onset of chest distress and palpitation after drinking alcohol. After the negative laboratory tests of plasma catecholamine and urinary vanillylmandelic acid, the F-FDG PET/CT revealed extremely intense metabolic activity in the bilateral adrenal lesions, and the subsequent I-meta-iodobenzylguanidine scintigraphy also showed increased radioactivity in the lesions. The pathology of surgery confirmed the diagnosis of bilateral pheochromocytomas.
一位 55 岁男性，在饮酒后突发胸痛和心悸，超声检查发现双侧肾上腺肿块。尽管进行了血浆儿茶酚胺和尿香草扁桃酸的阴性实验室检查，但是 F-FDG PET/CT 显示双侧肾上腺病变的代谢活性极高，随后的 I-间碘苄胍闪烁显像也显示病变部位放射性活性增加。手术病理证实为双侧嗜铬细胞瘤。
