1 A 42-year-old man experienced low-back pain and fever for 5 days.
A 42-year-old man experienced low-back pain and fever for 5 days. A and B, Axial T1-weighted (TR/TE, 600/16) (A) and axial T2-weighted (TR/TE, 4900/111) (B) MR images show an intraosseous lesion of T1-weighted low signal intensity and T2-weighted high signal intensity with an inner rim sign and an outer halo sign (arrow) near the upper endplate of S1. Note the limited amount of epidural soft-tissue inflammation (arrowhead). C.Y. Hsu et al. AJNR Am J Neuroradiol 2008;29: ©2008 by American Society of Neuroradiology
