title: [Ultrasonography and radiocholesterol scintigraphy in the topographic diagnosis of a pheochromocytoma (author's transl)].
abstract: Topographic diagnosis of adrenal pheochromocytoma were determined by ultrasonography in all 6 cases studied and by radiocholesterol scintigraphy in 6 out of 7 cases studied. It would appear that ultrasonography is preferable in the localization of an abdominal pheochromocytoma, whether adrenal or extra-adrenal. Intravenous urography along with rapid sequence nephrotomography and radiocholesterol scintigraphy, play a complementary role in confirming the topographic diagnosis. In case these methods prove unsuccessful or provide conflicting results, it is then possible to consider computed tomography, angiography and caval catheterization.
