At the level of the L1/2 intervertebral disc, there is an intra-dural extra-medullary ovoid lesion which demonstrates mild heterogeneous T2 hyperintensity. The lesion is avidly enhancing, with a central non-enhancing component corresponding to internal T2 hyperintense foci. There is an significant mass effect on the tip of the conus and proximal filum which are displaced anterolaterally to the left. Several cauda equina nerve roots are compressed over the right posterolateral aspect of the lesion. No other lesion identified.
L2/3 disc degeneration with a small right para central disc protrusion and annular fissure not resulting in significant canal stenosis. L2 vertebral body haemangioma noted.
Intra-dural extra-medullary lesion at the level of the L1/2 intervertebral disc consistent with a schwannoma with compression of the distal conus, filum and cauda equina.
