Scalloping describes an exaggeration of the concavity of the posterior surface of vertebral bodies secondary to tumoral growth seen in radiological images and is the result of bone erosion and deformation by tumor. It is associated with some types of tumors like Giant Schwannomas. These tumors represent type II, IVa and V of classification of spinal Schwannomas by Schridar and define high risk of recurrence. Management is based on the most complete resection possible and the affected spinal segment stability. This entity is rare and unusual in children and teenagers. At these ages it must be suspected that it could be secondary to syndromes as neurofibromatosis type 1 or 2. We present the case of 14 years-old boy with an expansive mass at L5-S1 lumbar segment with radiological scalloping on the bone affected. He was operated by laminectomy, tumoral resection and bilateral and lumbosacral bilateral arthrodesis. At the procedure intraoperative neurophysiological monitoring was used. Histological diagnostic was typical Schwannoma.
