1 A 27-year-old man with recurrent disk herniation confirmed by reoperation.
A 27-year-old man with recurrent disk herniation confirmed by reoperation. A, Precontrast axial T1- weighted MR image at L5-S1 level shows left subarticular recurrent disk extrusion with intermediate signal intensity (arrowhead). Thickened and posteriorly displaced left intradural nerve root (arrow) is noted. B, Postcontrast axial T1-weighted MR image reveals nonenhanced recurrent disk herniation. A combination of nerve root enhancement, thickening, and displacement (arrow) is also seen. Y.S. Lee et al. AJNR Am J Neuroradiol 2009;30: ©2009 by American Society of Neuroradiology
