Small well-defined ovoid intradural extramedullary lesion at the level of the L1-L2, compressing and displacing the cauda equina nerve roots. It elicits an iso-to slight high signal to the spinal cord on T1, inhomogeneous high signal on T2 and STIR with moderate heterogeneous enhancement on postcontrast sequences.
Moderate disc bulge at L3-L4 and L4-L5 with small subarticular disc herniation at L5-S1.
Case Discussion
MRI features of a small well-circumscribed intradural extramedullary lesion, pathologically proven myxopapillary ependymoma.
Myxopapillary ependymoma is considered a variant type of ependymoma, and the most common tumors of the cauda equina and/or conus medullaris region.
