Extraadrenal paragangliomas are tumors of the paraganglion system, usually arising from the carotid bodies, the glomus jugulare, or the glomus tympanicum. These tumors are capable of secreting catecholamines which can cause severe hypertensive crises. This paper reports a case of a patient who suffered a cerebral vascular accident due to hypertension resulting from a catecholamine-secreting infratemporal fossa paraganglioma. Any patient with a history of paroxysmal hypertension, headaches, and palpitations should be evaluated for a catecholamine-secreting tumor. Diagnosis and management of these tumors is best accomplished by a team including a radiologist, an endocrinologist, an anesthesiologist, a pathologist, an otolaryngologist--head and neck surgeon, and when the tumor invades the cranial cavity, a neurosurgeon. In this case, precise radiographic mapping of the tumor extent and its blood supply, control of hypertension with adrenergic blocking agents, and depletion of catecholamine stores using alpha-methyl-p-tyrosine allowed total extirpation through a craniofacial approach and a successful outcome.

Advances of neuroimaging, skull base technique and embolization improved outcome in patients who present with tumor of the glomus jugulare. Catecholamine secreting subgroup, however, is considered to be extremely high risk because of potentially serious complication of an intra- and perioperative hypertension crisis. The authors present detailed description of treatment strategies and perioperative management with a catecholamine secreting glomus jugulare.

Despite extensive growth, these tumors usually do not secrete active biogenic substances into the circulation in sufficient quantities to produce symptoms. When they do secrete large amounts of catecholamines, they will cause symptoms that mimic a pheochromocytoma.
