title: Local recurrence of pheochromocytoma in multiple endocrine neoplasia type 2A: a diagnostic and therapeutic challenge.
abstract: In a patient with multiple endocrine neoplasia type 2A (MEN2A), an inverted physiological ratio between urinary normetanephrines and metanephrines is an early marker of recurrence in epinephrine-secreting pheochromocytoma, and 131I MIBG treatment appears to be a useful therapeutic option in order to avoid multiple invasive surgical procedures in pheochromocytomatosis.
