Figure 1. Lumbar spine magnetic resonance imaging 2 weeks prior to the patient’s chiropractic visit. The sagittal (A) T2-weighted image shows disc displacements with radial fissures at L4/5 and L5/S1 (arrows). The axial T2-weighted image (B) highlight a disc displacement at L5–S1 (arrow). The L5/S1 disc displacement was interpreted by a board-certified medical radiologist as a broad-based disc protrusion from the posterocentral to left foraminal region and was noted to contain an abnormal T2 hyperintense annular signal consistent with annular fissure.
