[Pheochromocytoma and hyperthyroidism caused by amiodarone].

The authors report, in a 66 y. old patient, a case of pheochromocytoma, interesting in that its initial clinical picture is one of amiodarone-induced hyperthyroidism with orthostatic hypotension, and a persisting severe weight loss in spite of the improvement of the thyroid work-up is the indication of an adrenal tumor discovered on tomodensitometry. The accidental combination of these two endocrine diseases delays the already unusual manifestation of this pheochromocytoma and emphasizes the role of radiographic (tomodensitometry) and/or isotopic (MIBG) imaging in the "discovery" of these tumors.
