L5-S1 show reduction in intervertebral disc height with associated desiccation. A central disc extrusion resulting in severe spinal canal stenosis compressing on the cauda equina is also seen. The lateral recesses and neuroforamina are also narrowed resulting in compression of the exiting and traversing nerve roots. High T1 and T2 signal are seen at the inferior end plate of L5 and superior endplate of S1 consistent with Type 2 Modic changes.
The rest of the demonstrated lumbar intervertebral discs, spinal canal and neural foramina are unremarkable.
Features are those of degenerative disc disease causing disc extrusion at L5-S1 with compression of the cauda equina and bilateral L5-S1 nerve root compression.
