MR neurography examination of two FBBS patients. A Subsequent coronal 3D short tau inversion recovery sequence (3D STIR) images of one patient with no abnormalities. B Maximum-intensity projection of the 3D STIR images of the same patient (as depicted in A) showing no abnormalities of the lumbar plexus. C Sagittal T2-weighted MRI of a different patient showing a disk herniation occupying the left subarticular zone at level L4–L5 (white arrowhead). The white arrow depicts the coursing spinal nerve L4 on the left. D Coronal T1-weighted MRI of the same patient (as depicted in C, E) showing the disk herniation (white arrowhead) and left L4 spinal nerve (white arrow). E Coronal T1-weighted post-contrast MRI showing enhancing tissue (white dotted arrow) surrounding the disk herniation (white arrowhead). In addition, subtle perineural enhancement of the left L4 spinal nerve (white arrow) can be appreciated
