A 32-year-old female presented to another hospital with symptoms of nausea, vomiting, and headache, and was found to be hypertensive with orthostasis. Laboratory evaluation suggested the diagnosis of pheochromocytoma with elevated levels of serum metanephrines and nor-metanephrines. Before presentation to the hospital, she was not on any regular medications. Extensive cross-sectional and nuclear medicine imaging, including a head and neck CT, non-contrast CT and MRI of the abdomen and neck, 123I-meta-iodobenzylguanidine (123I-MIBG) whole-body scan, and exploratory surgery of the neck were unrevealing.
