Cranial and Spinal Meninges

Cranial and Spinal Meninges

The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

Area of Science:

Neuro-oncology
Pediatric Neurosurgery

Background:

Ependymomas typically arise infratentorially or intraventricularly, comprising 2-9% of CNS tumors.
Supratentorial pure cortical ependymomas are exceptionally rare, presenting diagnostic challenges regarding histogenesis.
These tumors are generally low-grade with a favorable prognosis following complete resection.

Observation:

A 14-year-old female presented with acute onset headache and convulsions.
The patient exhibited a rare supratentorial pure cortical ependymoma.

Findings:

Gross total excision of the ependymoma was achieved.
The patient received no adjuvant radiation therapy post-surgery.
Follow-up examinations revealed an uneventful recovery.

Implications:

Complete surgical resection is a primary curative treatment for supratentorial cortical ependymomas.
Adjuvant therapy may not be necessary in all cases, suggesting tailored treatment approaches.
This case contributes to understanding the management and prognosis of rare ependymoma subtypes.
