This case report details an unusual ependymoma exhibiting en-plaque spread throughout the entire ventricular system. Management challenges for this rare brain tumor presentation are discussed.

Area of Science:

  • Neuro-oncology
  • Neuropathology

Background:

  • Ependymomas are tumors arising from ependymal cells, typically found along the ventricular system or central canal.
  • While most ependymomas exhibit focal growth, rare behaviors and extensive spread patterns present unique clinical challenges.

Observation:

  • A 56-year-old male presented with symptoms indicative of increased intracranial pressure and truncal ataxia.
  • Imaging revealed an ependymoma with an extremely rare en-plaque growth pattern, involving the ependymal lining of the entire ventricular system.

Findings:

  • The tumor demonstrated diffuse, sheet-like spread (en-plaque) rather than a discrete mass.
  • This pattern involved the entirety of the brain's ventricular lining, a highly unusual manifestation for ependymoma.

Implications:

Related Experiment Videos

  • This case highlights the diverse and sometimes unexpected behavior of ependymomas.
  • Understanding rare growth patterns is crucial for accurate diagnosis, surgical planning, and effective management strategies for brain tumors.
