Presentation, Management, and Outcomes of Patients With Giant Pheochromocytoma
Authors' conclusion
Patients with giant PHEOs compared to referents were more symptomatic, had a higher degree of catecholamine excess, and had a higher rate of perioperative complications. Almost half of patients with giant PHEOs developed metastases, warranting close follow-up.
