34-year-old male with history of thigh pain 1 month ago. MRN images in coronal T2 (a), axial diffusion-weighted imaging (b), axial T2 fat suppression (c), and T1 postcontrast (d) show signal change with slight thickening and contrast enhancement of the left lateral cutaneous nerve (solid arrow), predominating at the level of the fibrous tunnel underlying the inguinal ligament and iliac crest (arrowhead), representing neuritis.
