Pre-operative magnetic resonance imaging. (A) Sagittal T1-weighted image revealing an intramedullary cystic-solid lesion in the conus medullaris. (B) Solid lesion demonstrating inhomogeneous enhancement following gadolinium injection. (C) T2-weighted image revealing the solid mass (large arrow) accompanied by a cranial cystic lesion (small arrow). (D) Coronary contrast-enhanced T1-weighted image showing the solid mass (large arrow) located exclusively within the conus medullaris (small arrow). (E) Coronary T2-weighted image indicating the additional cranial cystic lesion (large arrow) present in the spinal cord (small arrow).
