On axial (a) and coronal (b) T1-weighted images after administration of gadolinium the lesion located in the right temporal lobe shows slight rim enhancement (a, b, arrowheads). On sagittal (c) and axial (d) T1-weighted postcontrast images of the lumbar spine marked contrast enhancement of the spinal nerve roots in the cauda equina is visible (c, d, arrowheads). On-going chemoradiotherapy. The hyperintense signal intensity changes have markedly increased on axial T2-weighted images (a, arrowhead)
