Nerve compression and entrapment syndromes are classic examples of the integrated role of radiologists and clinicians in achieving difficult but accurate diagnoses. The pathology of nerves can only be understood after evaluating the normal architecture and imaging characteristics of nerves. Understanding the correlation of the pathophysiology of nerve compromise with electromyographic findings and imaging findings allows for greater comprehension of a difficult topic. Particularly in the elbow, there are multiple potential areas of nerve entrapment and compression that can be evaluated perhaps best with magnetic resonance imaging.
