Lumbar extrusion with sequestered fragment ( RID6163 )
Patient had fusion surgery and is hypolordotic to the point of reversal with resulting kyphosis. Large mass below the L 3/4 level to the left of midline associated with posterior disc space narrowing. Hard to say how much mass effect is due to hemorrhage vs. disc. I read it out as disc. If f/u I will update.
