What do we miss without contrast in patients with flank pain?

Published:September 09, 2015DOI:https://doi.org/10.1016/j.ajem.2015.09.002
      Flank pain is a common complaint in the emergency department, and the most frequent cause of flank pain is urolithiasis. Spontaneous renal artery dissection and renal artery thrombosis are rare causes of abdominal pain which can result in renal parenchymal injury.

The present report describes 2 patients admitted to the emergency department because of acute flank pain who were diagnosed with renal infarction.
