title: Giant extra-adrenal pheochromocytoma: magnetic resonance imaging with gadolinium-DTPA enhancement.
abstract: A case report of a 35-yr-old male presenting with moderate hypertension and a giant extra-adrenal pheochromocytoma is discussed. The patient was treated by chemotherapy and surgery with regression of the lesion and clinical relief of symptoms. Initial magnetic resonance imaging (MRI) with gadolinium-DTPA enhancement revealed a large complex pelvic mass. Follow-up examination following chemotherapy three months later demonstrated partial regression. The MRI findings and the pattern of gadolinium-DTPA enhancement are discussed.
