[Pheochromocytoma of the organ of Zuckerkandl].

The authors report the case of a pheochromocytoma of the organ of Zuckerkandl in a 46 year old man. The clinical presentation was severe paroxysmal hypertension; the tumour was located by arteriography, CT scanning, and by scintigraphy with iodine labelled benzylguanidine. The blood pressure returned to normal after surgery. The embryological, anatomical and physiological features of the organ of Zuckerkandl are reviewed: the authors discuss briefly the modern methods of diagnosis and localisation of the tumour.
