Abstract

A previously healthy 44-year-old woman, with no notable medical history developed left flank pain. To rule out left renal infarction, enhanced abdominal computed tomography (CT) was done and a wedge shaped hypointense lesion was identified in the left posteromedial aspect of the interpolar region. Renal angiography revealed an isolated renal artery dissection that was causing renal infarction due to narrowing of the main stem of the left renal artery. The patient experienced pain with severe uncontrolled hypertension. The patient was successfully treated by percutaneous angioplasty and renal artery stenting.

Keywords: Renal artery dissection, Renal infarction
