A 49-year-old woman with a history of previous carpal tunnel surgery and median nerve injury. A 49-year-old woman with a history of previous carpal tunnel surgery and median nerve injury. A, The median nerve was re-explored in the hand followed by neurolysis and nerve tube placement (short arrows). The patient did not recover nerve function following surgery. B and C, MR imaging examination 5 months after surgery shows no significant nerve regeneration and empty fluid-filled nerve tubes (curved arrows). D, Re-exploration demonstrated end-bulb neuromas (wavy arrow), and nerve grafting was performed. A. Chhabra et al. AJNR Am J Neuroradiol 2010;31:1363-1368 ©2010 by American Society of Neuroradiology
