case_images: (a) Sagittal T2-weighted magnetic resonance imaging (MRI): L4-L5 interspinous ligament degeneration/sclerosis (e.g., hypointense streak (arrow) and severe canal stenosis. (b) Axial T2-weighted MRI upper L5 level: lumbar canal stenosis with severe thecal sac compression/hypertrophied ligamentum flavum/facet arthrosis. (c) Sagittal noncontrast computed tomography section lumbosacral spine: sclerosis/flattening of spinous processes of L4/L5 (arrow). (d-f) Axial T1 contrast MR: abnormal ill-defined enhancement - "atypical" Baastrup's disease (arrows).

case_images: The contrast MR revealed soft tissue enhancement of the paraspinal musculature, and dorsal to the thecal sac, an inflammatory and/or infectious compressive process [Figure 1].
