Skeletal Radiol. 2015 Mar;44(3):457-61. doi: 10.1007/s00256-014-2006-3. Epub 2014 Sep 24.


Spontaneous nerve torsion is a rare cause of nerve palsy. We describe a case of nerve torsion affecting the radial nerve in order to inform radiologists of the existence of this condition and subtle features on cross-sectional imaging that can suggest the diagnosis preoperatively.
