Adenomatoid tumor of adrenal gland in a 63-year-old male. His pfNMN was 476.3pmol/L, slightly above the normal range, and was defined as borderline. (A) Axial CT image shows a hypointense tumor at the right adrenal gland (arrow). (B) The tumor shows a moderate uptake of ⁶⁸Ga-DOTA-TATE in the CT and PET fusion image (arrow). The SUV_max was 10.2, SUVR was 0.9, and KS score was 2. This tumor was diagnosed as PCC visually before surgery. Histologic results after surgery indictaed an adenomatoid tumor of the adrenal gland. pfNMN, plasma-free normetanephrine; CT, computed tomography; ⁶⁸Ga-DOTA-TATE, ⁶⁸Ga-DOTA(0)-Tyr(3)-octreotate; PET, positron emission tomography; SUV_max, maximal standardized uptake value; SUVR, ratio between the SUV_max of the lesion and the SUV_mean of the liver; SUV_mean, mean standardized uptake value; KS, Krenning scale; PCC, pheochromocytoma.
