A 47-year-old woman with a nonenhancing WHO grade III anaplastic astrocytoma. Her chief symptoms were a left upper extremity tingling sense and weakness, which had gradually extended from the distal to the proximal portion. Thereafter, the same symptoms occurred in both lower extremities. A and B, Axial and sagittal T2-weighted MR images show an ill-defined slightly hyperintense mass at cervical spinal cord. C, The mass is isointense to the spinal cord on sagittal T1-weighted images. D and E, Contrast-enhanced axial and sagittal T1-weighted images show a nonenhanced mass.
