Hourglass neurinoma resulted in symptoms of polyneuropathy
Distal symmetric polyneuropathy (DSP) is a common condition where limited diagnostic evaluation is usually required. We present a case story of a 50-year-old male who had symptoms of DSP, but electrodiagnostic testing suggested a more proximal lesion, and m agnetic resonance imaging showed a spinal nerve root schwannoma. The patient recovered completely after surgery. This case exemplifies relevant use of electrodiagnostic testing. Based on a recent review, we briefly mention atypical features which should prompt further testing, emphasizing that evaluation should be reserved to a limited group of patients.
