Extraadrenal pheochromocytoma with renal artery "pseudostenosis"-an important pitfall.
Pheochromocytoma and renal artery stenosis are two common causes of surgically correctable childhood hypertension that may coexist. We describe a case of extraadrenal pheochromocytoma with left upper polar renal artery pseudostenosis. The tumor was excised, preserving the accessory renal artery and kidney. The child was normotensive and did not require drugs postoperatively. Radiologic appearance of stenosis does not necessarily mean fixed renal artery stenosis, especially with a pheochromocytoma because it may exist as a result of vasospastic effects of the pheochromocytoma. Incorrect diagnosis may result in untoward risk and unnecessary procedures for the patient, hence the need to remember this pitfall.
