Summary

Two central neurocytoma cases disseminated despite lacking anaplastic features. Radiologic findings, including extraventricular extension, were crucial for diagnosis before surgery and radiation therapy.

Area of Science:

  • Neuro-oncology
  • Neurosurgery
  • Radiology

Background:

  • Central neurocytoma is a rare brain tumor.
  • Histopathologic features of anaplasia are typically associated with aggressive behavior.

Purpose of the Study:

  • To report two cases of central neurocytoma with unusual dissemination.
  • To highlight the significance of radiologic findings in diagnosing and managing these tumors.

Main Methods:

  • Case report of two patients with central neurocytoma.
  • Review of histopathologic findings.
  • Analysis of pre-operative CT and MR imaging.

Main Results:

  • Both cases lacked histopathologic features of anaplasia.

  • Tumor dissemination occurred after surgery and radiation therapy.
  • Pre-operative imaging revealed extraventricular tumor extension in both cases.

    • Conclusions:

    • Central neurocytomas can disseminate even without anaplastic features.
    • Radiologic findings are critical for identifying potential for spread.
    • Careful pre-operative assessment and follow-up are essential.
