Intradural Extramedullary Spinal Sarcoidosis Mimicking Meningioma

Abstract EN

Background.

Spinal sarcoidosis is a rare subgroup of neurosarcoidosis.

Although most sarcoid lesions develop in the intramedullary compartment, intradural extramedullary (IDEM) spinal sarcoidosis is an extremely rare entity.

Case Presentation.

We herein report a case of IDEM spinal sarcoidosis mimicking a meningioma.

A 32-year-old man presented to the hospital with clumsy hands and was unable to walk without assistance.

Magnetic resonance imaging (MRI) of the cervical spine revealed a dural tail sign that is common in meningiomas.

The patient underwent gross total resection.

The pathological findings consisted with a sarcoid leision of the spinal cord.

The patient’s myelopathy recovered after surgery.

Conclusions.

Physicians should be alert for the possibility of IDEM sarcoidosis mimicking a meningioma in the differential diagnosis of IDEM spinal cord tumors.
