title: Spontaneous renal artery dissection diagnosed by unenhanced magnetic resonance angiography: case report.
abstract: A 47-year-old patient is presented who was admitted to the emergency department with complaints of right-sided flank pain and hypertension. His creatinine and glomerular filtration rate were 2.5 mg/dl and 37 ml/min respectively, so that contrast media administration was contraindicated. The unenhanced magnetic resonance angiography image obtained with 3D in-flow inversion recovery sequence showed right renal artery dissection, without aortic dissection. Selective renal angiography confirmed the diagnosis and a stent was placed in the renal artery. The patient was free of pain after stenting, with normalized laboratory values and blood pressure.
