Summary

Benign tumors can cause radial nerve paralysis, with lipomas being the most common cause. Surgical removal typically leads to good patient outcomes, and electromyography aids diagnosis when needed.

Area of Science:

  • Orthopedics
  • Neurology
  • Oncology

Background:

  • Radial nerve paralysis can result from various medical conditions.
  • Tumors are an uncommon but significant cause of radial nerve dysfunction.
  • Understanding the types and outcomes of tumor-induced radial nerve paralysis is crucial for diagnosis and treatment.

Purpose of the Study:

  • To present ten new cases of radial nerve paralysis caused by tumors.
  • To review 38 previously reported cases of tumor-related radial nerve paralysis.
  • To analyze the types of benign tumors associated with radial nerve paralysis and their outcomes.

Main Methods:

  • Case series presentation of ten patients with radial nerve paralysis due to tumors.
  • Literature review of 38 previously reported cases.
  • Analysis of tumor types, including lipomas, neurofibromas, ganglions, neuromas, fibromas, and neurilemomas.
  • Electromyography utilization for diagnostic challenges.

Main Results:

  • Ten new cases of radial nerve paralysis caused by benign tumors were identified.
  • Lipomas constituted the majority (35 cases) of the reviewed tumors.
  • Other reported tumors included neurofibromas, ganglions, neuromas, fibromas, and neurilemomas.
  • Electromyography proved valuable in cases with diagnostic difficulties.

Conclusions:

  • Benign tumors are a recognized cause of radial nerve paralysis.
  • Lipomas are the most frequent tumor type associated with this condition.
  • Surgical intervention for tumor removal generally yields favorable postoperative results.
