Entrapped lumbar nerve root in pseudomeningocele after laminectomy: report of three cases.
The authors report three patients with symptomatic postlaminectomy pseudomeningocele. At operation a loop of a nerve root was found to be trapped within the dural defect. All three patients exhibited a delayed onset of radicular symptoms and signs after disc surgery. The pseudomeningocele was demonstrated computed tomography and myelography, but the entrapped root could be identified only at operation.
