title: Basilar artery aneurysm simulating pheochromocytoma.
abstract: Stimulation of sympathetic vasomotor centers by lesions in the posterior fossa has been described in humans and animals. We describe a patient with a pheochromocytoma-like syndrome and a basilar artery aneurysm. Repair of the aneurysm was followed by disappearance of hypertensive episodes. Posterior fossa lesions must be considered in patients with hypertensive crises when diagnostic procedures do not indicate an adrenal or extra-adrenal pheochromocytoma.
