Thoracic spinal epidural lipomatosis associated with adolescent scoliosis

Although a variety of neural axis abnormalities in association with idiopathic scoliosis have been reported, there are no documented cases of spinal epidural lipomatosis (SEL) in a child with scoliosis. An otherwise healthy, neurologically intact 14-year-old girl presented with spinal deformity. Radiographs confirmed a left thoracic, right lumbar Lenke class 5CN scoliosis. Preoperative magnetic resonance imaging (MRI) demonstrated extensive SEL in the thoracic spine. She underwent posterior spinal fusion with segmental instrumentation using bony anchors that did not violate the spinal canal. Intraoperative spinal cord monitoring and postoperative clinical course were uneventful. SEL should be added to the list of potential abnormalities to be looked for in children with spinal deformities undergoing preoperative MRI of the neural axis.
