Magnetic resonance neurography (MRN) is a relatively new imaging technique that is highly sensitive in detecting lesions in the peripheral nerves. We studied six cases of brachial plexopathies in which MRN played a pivotal role in making the correct diagnoses. ⋯ MRN in all patients showed edema, thickening, and T2 hyperintensities localized to the brachial plexus region. We conclude that MRN is a useful technique in evaluating patients with brachial plexus lesions, particularly in cases of brachial plexitis, where conventional magnetic resonance imaging is generally normal.
