Pheochromocytoma

  • Etiology: catecholamine-secreting tumors derived from chromaffin cells, when found outside adrenal gland are called paraganglioma
  • Imaging: solid adrenal mass
  • Clinical: elevated metabolites of norepinephrine and epinephrine (normetanephrine and metanephrine), no evidence that IV administration of modern (non-ionic) iodinated or gadolinium-based contrast material increases the risk of hypertensive crisis in patients with pheochromocytoma

Cases of Pheochromocytoma
