case_images: T1-weighted and inhomogeneous hyperintense lesion on the T2-weighted study that was homogeneously enhanced with contrast [Figures 1 and 2]. The lesion compressed the lateral/foraminally exiting L1-L3 nerve roots and the right kidney.
case_images: Magnetic resonance imaging examination of the (a) axial, (b) sagittal, and (c) coronal section of the T2-weighted sequence showed an extradural mass lesion that extended to the peritoneal cavity.
