Lysis of epidural adhesions is an interventional procedure performed to treat refractory low back pain or radicular pain due to epidural scarring. A 39-year-old female with a diagnosis of failed back surgery syndrome underwent lysis of epidural adhesions using a Racz catheter. She developed acute monoplegia of her right lower extremity immediately after the procedure. Radiographic imaging did not reveal an epidural hematoma. Motor and sensory function in the right lower limb returned after 5 days. Large volumes of fluid injected during neuroplasty could have caused transient nerve injury from compression within loculated epidural compartments.
