Abstract:
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.
