Varied Presentation of Pheochromocytoma: Surgical and Anesthetic Management of Three Different Cases

Pheochromocytoma, the neuroendocrine tumors arising from chromaffin tissue, poses a very significant challenge to the anesthetists, especially when they are undiagnosed. They present with varied symptoms and sometimes they are silent and nonfunctional. The anesthetic management of these tumor excisions varies depending on the surgical approach and perioperative hemodynamic instability encountered by the anesthetist. Here, we are presenting three different cases of pheochromocytoma who underwent adrenalectomy in our hospital with varied presentation and their successful anesthetic management.
