Abstract
Lumbar pseudomeningocele is a common complication of spinal surgery. It is caused by dural defect, and it consists of extradural collection of cerebrospinal fluid communicating with subarachnoid space. Usually it is small, asymptomatic, and self-limiting. In case of persistence, common treatments include bedrest, puncture and compressive dressing, subcutaneous or subarachnoid lumbar drainage, surgical re-exploration for durotomy closure, and blood patch. Fast-resorbing polymer mesh has been recently used for closure osseous gap in adult patients who developed giant pseudomeningocele following laminectomy. We report the case of a 16-year-old girl, affected by spinal dysraphism, who developed a persistent giant lumbar pseudomeningocele after repeated surgery for detethering of the spinal cord and removing of spinal lipomyelomeningocele. She was finally treated with fast-resorbing polymer mesh, to fill the gap of the posterior osseous defect and to provide support for the thecal sac. For our best knowledge, this is the first pediatric case reported in literature on this kind of reconstruction. In complex cases of pseudomeningocele, implant of fast-resorbing polymer mesh may represent an option also in pediatric patients.
