Pheochromocytomas and Paragangliomas


Biochemical testing is the cornerstone of the diagnosis of pheochromocytoma, but that is only one part of the story for patients with these tumors. This lecture highlights the physiology behind the symptoms of catecholamine excess and reveals how biochemical testing fits into the larger scheme of patient care, including surgical removal of these tumors.

Originally presented on September 22, 2014, in Salt Lake City, Utah.
