Figure 1:

Preoperative magnetic resonance imaging (MRI) with gadolinium showed an expansile intramedullary tumor of thoracic cord and conus medullaris with irregular heterogeneous enhancement and some cystic changes on sagittal (a and b) and axial (c) views in a 9-year-old patient with severe thoracolumbar scoliosis (d). After surgical treatment, 2 years follow-up MRI reveals an evidence of minimal cord herniation toward laminectomy sites and intramedullary cystic changes (sagittal T2 sequence), (e) with minimal enhancement on sagittal (f) and axial (g) views.
