Posterior Epidural Migration of a Lumbar Disc Herniation Causing Cauda Equina Syndrome: A Case Report.

We report an uncommon case of posterior epidural migration of a lumbar disc fragment (PEMLDF) in a patient presenting with acute, progressive back pain, radiculopathy, and weakness. PEMLDF can be mistaken for neoplastic or infectious etiologies on imaging, presenting a diagnostic and management challenge. Our patient underwent an urgent decompressive lumbar laminectomy, which revealed a PEMLDF intraoperatively. He went on to achieve good neurologic recovery.
