Hyperaldosteronism secondary to spontaneous renal artery dissection (renovascular): A case report and review of the literature.

Spontaneous renal artery dissection refers to endarterial dissection of the renal artery that occurs with unknown cause. Herein, we describe a 45-year-old woman who presented with pain in her right flank and abdomen together with elevated blood pressure and hypokalemia. We made the diagnosis of an enhanced renin-angiotensin-aldosterone system and obtained enhanced abdominal computed tomography images, which showed right renal artery dissection with a large false lumen and narrowed true lumen. This dissection was complicated by partial renal infarction. The patient underwent right nephrectomy and experienced resolution of her symptoms, especially of the hypertension and hypokalemia.
