8 sections · 48 slides
Overview
- What you will learn
Understanding the Tumor
What it is, where it grows, and who gets it
- What is a spinal meningioma?
- Spinal meningiomas by the numbers
- Who gets them, and where
- Ventral thoracic meningioma compressing the cord
How Patients Present
A slow, quiet course until the cord is squeezed
- The quiet, delayed onset
- Symptoms depend on level
- What the exam shows
Diagnosis and Imaging
MRI is the gold standard
- Reading the MRI
- Intradural extramedullary meningioma on MRI
- Calcification and other clues
- Calcified spinal meningioma on MRI
Classifying the Tumor
Position relative to the cord guides everything
- The Elsberg map (1925)
- Why most are lateral
- What predicts a good result
Planning the Operation
Choosing the approach and preparing the patient
- Choosing the avenue of approach
- Surgical approaches by tumor location
- Getting the patient ready
The Operation, Step by Step
From positioning to gross total resection
- Positioning on the table
- Finding the right level
- Exposing the spine
- The laminectomy
- Seeing the tumor and widening access
- Hemostasis, then opening the dura
- Identifying the tissue planes
- Removing the tumor
- Ventrolateral L1 meningioma and its resection
- Achieving a complete removal
- The dural attachment debate
- Dural handling across published series
- Repairing the dura and closing
Outcomes and Recovery
Why this is one of the most rewarding spinal operations
- What determines the result
- Reported surgical outcomes across series
- Neurological recovery is the rule
- Outcomes across reported series
- Complications and delayed deficits
- Recurrence and poor-outcome predictors
- Key takeaways
