Intramedullary ependymoma: Microsurgical resection technique.

Area of Science:

• Neurosurgery
• Oncology
• Spinal Cord Research

Background:

• Spinal ependymomas are common primary intramedullary tumors, often slow-growing.
• These tumors typically present as well-defined lesions with clear surgical margins.
• Complete surgical removal is often achievable and curative, but functional preservation is paramount.

Purpose of the Study:

• To present a detailed surgical technique for resecting intramedullary ependymomas.
• To emphasize the preservation of spinal cord function during surgical intervention.
• To provide an overview of current management strategies for spinal ependymomas.

Main Methods:

• A posterior median sulcus surgical approach was utilized.
• The technique focuses on safe dissection and resection of the intramedullary tumor.
• Intraoperative neurophysiological monitoring is implicitly crucial for functional preservation.

Main Results:

• The described posterior median sulcus approach facilitates safe resection of spinal ependymomas.
• This technique aims to achieve gross-total resection while minimizing neurological deficit.
• Successful application of the technique allows for potentially curative treatment.

Conclusions:

• The posterior median sulcus approach is an effective method for surgically managing spinal ependymomas.
• Prioritizing spinal cord function preservation is essential for optimal patient outcomes.
• This technique contributes to the armamentarium for treating these challenging tumors.
