Paragangliomas are uncommon tumors arising from the neuroendocrine elements of the paraganglia. Their successful management is associated with many problems. We herein present the findings of a 22-year-old man in whom a paraganglioma was incidentally found and in which the clinical and previous operative behavior was functioning desensitization. As a result, preoperative medication was not performed; however, during the tumor resection the patient demonstrated hemodynamic instability.
