%X <B>UNASSIGNED: </B>A 17-year-old boy with Von Hippel-Lindau syndrome presented with hypertension, raised plasma catecholamines, and MRI findings of a new pancreatic tail lesion and 2 stable right adrenal lesions concerning for functional neuroendocrine tumors. A 68 Ga-DOTATATE PET/CT demonstrated intense tracer avidity within the pancreatic lesion with minimal uptake in the adrenal lesions. Conversely, a 123 I-MIBG SPECT/CT study demonstrated high-grade tracer uptake within the adrenal lesions, with no significant uptake appreciated in the pancreatic lesion. The adrenal lesions were resected, and pathology was consistent with pheochromocytoma. Plasma catecholamines returned to within the normal range and hypertension resolved.
