Area of Science:

Neurosurgery
Spinal Oncology
Pathology

Background:

Extradural spinal meningiomas are uncommon tumors with unclear pathophysiology.
These tumors can present with symptoms such as low back and leg pain.

Purpose of the Study:

To present a case of an unusual extra-intradural spinal meningioma.
To emphasize the importance of distinguishing extradural meningiomas from other spinal tumors for surgical planning.

Main Methods:

Case presentation of a 49-year-old woman with a T12 level spinal mass.
Magnetic resonance imaging (MRI) for diagnosis.
Surgical removal including T12 total laminectomy, durotomy, and dural excision.
Pathological examination confirming psammomatous meningioma.

Keywords:

Published on: June 28, 2024

Main Results:

A 1.8-cm mass with rim enhancement was identified at the T12 level, extending into the T12-L1 foramen.
The mass had both extra-intradural components, requiring complex surgical resection.
Pathology confirmed a psammomatous meningioma.

Conclusions:

Accurate differentiation of extradural meningiomas is crucial to avoid misdiagnosis and guide operative strategy.
Total excision is considered essential for the long-term prognosis of extradural meningiomas, although long-term outcomes remain unclear.
