Washington University Experience | PERIPHERAL NEUROPATHY | 1 NORMAL NERVE ANATOMY | 7 Biopsied Nerves Other than Sural | 5A1 Axon loss, AIN nerve, (Case 5) Plastic 1
Case 5 History ---- The patient is a 72-year-old male with a history of diabetes, mononeuropathy multiplex in the setting of VZV reactivation, and few months of left greater than right upper limb pain and weakness following cervical spine surgery, clinically suspicious for post-surgical inflammatory neuropathy syndrome. EMG/NCV showed evidence of left brachial plexopathy. MRI showed abnormal intrinsic signal and decreased muscle bulk of several left shoulder girdle muscles, compatible with acute and chronic denervation, consistent with brachial plexus neuritis (Parsonage-Turner syndrome). Operative procedure: Biopsy of pronator quadratus muscle, left anterior interosseous nerve. ----
5A1,2 In this case there may be simultaneous axonal degeneration/regeneration superimposed on the AIN nerve clusters. (Toluidine-blue stained one-micron thick plastic embedded section)
