Radiologic Approach to the Patient with Suspected Pheochromocytoma

Abstract

Thirty-four patients with 37 pheochromocytomas were studied by catheter angiography and results of these studies were reviewed. The radiographic approach to the patient with suspected pheochromocytoma is discussed. Following clinical and laboratory work-up and general radiographic procedures (urography with adrenal laminagraphy), arteriography with careful monitoring is indicated. Selective catheterization is recommended before aortography. Adrenal venography is necessary if all arterial studies are negative. This protocol permits safe and accurate evaluation of patients suspected of having pheochromocytoma.
