At the L3/L4 level, there is a well- defined intradural lesion that demonstrates homogeneous T2 hypointensity and intermediate T1 intensity. The cauda equina is displaced peripherally around this mass. Diffuse homogeneous enhancement post gadolinium administration. There are no peritumoral cysts or haemosiderin capping. The neural exit foramina are normal bilaterally throughout the lumbar levels.
Conclusion:
Although the shape is more typical of schwannoma or ependymoma, the T2 hypointensity favours meningioma.
