Twenty-two months ago, the first lumbosacral magnetic resonance imaging (MRI) with and without gadolinium revealed a well-defined intradural extra-axial mass that homogenously enhanced posterior to the L1/2 disc space (a). There was also an L2/3 disc herniation (b and c). Twenty-two months later, the second MRI showed the mass migrated posterior to the L3 vertebral body, while the L2/3 disc herniation remained the same (d)

The first lumbosacral magnetic resonance imaging (MRI) scan revealed an intradural extramedullary mass with homogeneous enhancement at the L1/2 level accompanied by an L2/3 disc herniation [Figure 1a-c]. The second MRI, 22 months later, showed the tumor had migrated inferiorly and was now behind the L3 body [Figure 1d].
