Extra-adrenal pheochromocytoma: an unusual cause of deep vein thrombosis.

Abstract

We report a case of extra-adrenal pheochromocytoma within the organ of Zuckerkandl that presented initially with a left iliofemoral deep venous thrombosis (DVT). At the time of presentation, the DVT was thought to be idiopathic as no underlying cause was detected. Subsequently, because of a series of medical events, the patient was further investigated. This led to a diagnosis of extra-adrenal pheochromocytoma. We discuss the management of patients presenting with DVT, the nature of pheochromocytoma within the organ of Zuckerkandl, and problems relating to its diagnosis.
