This study reports the first case of a cellular intraventricular schwannoma in the fourth ventricle. Microsurgery achieved complete removal, confirming this rare brain tumor can be successfully treated.

Area of Science:

  • Neuro-oncology
  • Neurosurgery
  • Neuropathology

Background:

  • Intraventricular schwannomas are exceptionally rare brain tumors.
  • Schwann cell tumors typically arise along peripheral nerves or cranial nerves.

Observation:

  • A 71-year-old female presented with an incidentally discovered fourth ventricle tumor.
  • Imaging revealed a solitary, contrast-enhancing, exophytic mass in the fourth ventricle.

Findings:

  • Histopathology confirmed the tumor as a primary intraventricular cellular schwannoma.
  • Complete tumor resection was achieved via microsurgery using a suboccipital craniotomy.

Implications:

  • This case highlights that schwannomas, though rare, can occur within the brain ventricles.
