Figure 2. (A) Sagittal T2-weighted sequence shows a heterogeneously hyperintense mass with multifocal internal hypointensities filling the entire spinal canal of the lumbar and upper sacral region. At its superior aspect, the mass abuts and superiorly displaces the conus medullaris. The cauda equina nerve roots are not identified and in view that this mass completely fills the lumbosacral spinal canal, are likely compressed or involved. There is subsequent spinal canal expansion with areas of scalloping. (B, C) Sagittal T2-weighted sequences demonstrate that the mass extends bilaterally through expanded lumbosacral neural foramina to the prevertebral/perivertebral and presacral regions with subsequent displacement of presacral vessels and bilateral psoas muscles. (D) Coronal T2-weighted sequence shows bilateral retroperitoneal involvement extending just inferior to the inferior poles of the bilateral kidneys. (E, F) Sagittal T1-weighted postcontrast fat-sat sequences also show that the mass has a heterogeneous enhancement pattern, which also involves various posterior vertebral bodies at the inferior lumbosacral region, as evidenced by contiguous vertebral body enhancement.
