What is the typical demographic affected by spinal meningiomas?
Spinal meningiomas have a peak incidence is in the fifth and sixth decades. Interestingly, and unlike intracranial meningiomas, in the adult population, females are approximately ten times more commonly affected than males. In children, there does not appear to be a sex predilection.
How are spinal meningiomas distributed along the spinal canal?
Spinal meningiomas are also not distributed evenly along the canal: cervical spine (15%), thoracic spine (80%), lumbosacral spine (uncommon).
What phakomatosis is associated with increased incidence of spinal meningiomas?
There is an increased incidence of spinal meningiomas in patients with neurofibromatosis type 2, and in fact in the paediatric population, meningiomas uncommonly occur outside of the setting of NF2.
A homogeneously enhancing intra-dural, extramedullary mass with a broad dural base, dural tail and in the vertebral canal anteriorly at the level of T1 is demonstated. It results in significant cord compression with flattening of the cord and obliteration of the CSF space. The cord is displaced posterolaterally to the right. Mild associated cord signal hyperintensity is observed.
Normal bone marrow signal. Multiple endplate focal compression fractures consistent with Schmorl's nodes.
