Spinal meningioma
Epidemiology
Classification
Pathology
Most spinal meningiomas are benign, with greater than 95% being classified as WHO grade I lesions, although clear cell meningiomas (a WHO grade II histological variant) have a predilection for the spine.
They are believed to originate from the denticulate ligaments.
Clinical Features
The majority of patients present with motor impairments as a result of compression of the spinal cord. Less common presentations include sensory deficits, pain and sphincter dysfunction.
