Area of Science:

  • Neurosurgery
  • Orthopedic Oncology
  • Musculoskeletal Radiology

Background:

  • Neurilemomas, also known as schwannomas, are nerve sheath tumors.
  • Intramuscular location is less common than superficial locations.
  • Understanding clinical presentation is key for diagnosis.

Purpose of the Study:

  • To analyze the clinical features of intramuscular neurilemomas.
  • To describe the presentation, diagnosis, and outcomes of these tumors.

Main Methods:

  • Retrospective analysis of twelve patients with intramuscular neurilemoma.
  • Diagnosis confirmed by magnetic resonance (MR) imaging and surgical operation.
  • Data collected on tumor location, patient demographics, symptoms, and follow-up.

Main Results:

  • Neurilemomas were found in the limbs and back.
  • Patients presented with palpable masses, occasionally with slight tenderness.
  • No neurological deficits or symptoms were observed.
  • Mean patient age was 41 years.
  • No postoperative complications or tumor recurrence were reported after a mean follow-up of two years.

Conclusions:

  • Intramuscular neurilemomas typically present as asymptomatic or mildly tender masses.
  • They do not usually cause neurological symptoms.
  • Surgical excision is effective with no recurrence observed in this cohort.
