Epidural venous plexus engorgement due to inferior vena cava thrombosis resulting in cauda equina syndrome: Case report and literature review.
Background: Epidural venous plexus congestion at L5-S1 due to inferior vena cava (IVC) thrombosis led to an acute cauda equina syndrome (CES). Laminectomy to rule out an epidural abscess, allowing for resection of the dilated veins, led to immediate symptom resolution.
Case Description: A 47-year-old male presented with acute urinary retention and left greater than right lower extremity paresis of 2 weeks duration. Magnetic resonance imaging (MRI) revealed a contrast-enhancing space-occupying anterior epidural L5-S1 level lesion resulting in cauda equina compression. As the patient was septic, he underwent an emergency laminectomy for a presumed epidural abscess. Intraoperative findings, however, documented a markedly dilated epidural venous plexus secondary to a newly diagnosed IVC thrombus. One day postoperatively, the patient was symptom-free and neurologically intact.
Conclusions: Here we report a patient who uniquely presented with a CES characterized by acute paraparesis. This was attributed to a massively engorged anterior lumbar epidural venous plexus attributed to newly diagnosed IVC thrombus.
