Abstract

The role of an accessory renal artery in the pathogenesis of hypertension is still
controversial. In this report, we describe a previously healthy 16-year-old girl with an accessory right
renal artery who presented with hypertensive urgency (no progressive target organ dysfunction). Initial
workup other than hypercholesterolemia and mild proteinuria was normal with no signs of other
target organ damage. Further evaluation was aimed at determining the possible cause of secondary
hypertension. High normal plasma renin with elevated plasma aldosterone led to a suspicion of renovascular
hypertension. Magnetic resonance angiography and later computed tomography angiography
showed two non-stenotic right renal arteries. Another diagnostic workup was normal. A satisfactory
blood pressure control was eventually achieved with combination therapy including angiotensin-converting
enzyme inhibitor. We conclude that although non-stenotic, an accessory renal artery should
be considered as a possible cause of renovascular hypertension in children and adolescents even in the
absence of hyperreninemia.
