  • Abstract
  • Look Inside

 The patient was a 15 year-old female. Preoperative MRI showed a cyst, flow void, calcification, and spinal cord enlargement with hemorrhage. The spinal cord was inhomogeneously enhanced from the Th4 to the Th11 level. The preoperative differential diagnosis was ependymoma, astrocytoma, or AVM. The intraoperative histological diagnosis was ependymoma, but the postoperative diagnosis was pilocytic astrocytoma. Preoperative diagnosis was difficult because of differences in the imaging findings. The ability to make a precise histological diagnosis of intramedullary tumors by currently available imaging techniques remains elusive.
