Dural ectasia and cauda equina syndrome: A rare complication of long-standing fusion
2018
The clinicoradiological combination of cauda equina syndrome (CES) and dural ectasia is rare and has been described in a few of patients with ankylosing spondylitis (AS). Simultaneous occurrence of these entities in the absence of AS and in patients with long-standing spinal fusion is extremely rare. We present a case of dural ectasia and CES occurring as a long-term complication of instrumented spinal fusion and discuss the pathogenesis, imaging findings, and management options of this elusive disease process.
