Clinical case presenting a patient suspicious for PPGL. The patient had a history of hypertension. Preoperative normetanephrines were 1.93 and 1.59 (< 1.07 nmol/L) and metanephrines 0.23 and 0.23 (< 0.45 nmol/L). Pathology confirmed a 15-mm pheochromocytoma with a PASS score of 7. The images show transaxial slides of the adrenal glands on a contrast-enhanced CT (left, image A), superimposed on a contrast-enhanced CT for FDOPA PET/CT (middle, image B) and DOTATOC PET/CT (right, image C). Image B shows high, FDOPA uptake in the right adrenal gland correlating to a 15-mm nodular, contrast-enhanced structure (not hypervascular). No FDOPA uptake in the left adrenal gland and no CT correlate. Image C shows the high physiologic uptake of DOTATOC in both adrenal glands, as well as physiological uptake in the liver and spleen. Blood pressure and plasma metanephrines were normalized after surgical resection
