Figure 3b. Figures 2, 3. (2) CT scan shows dense bone at the center of the tumor with bony spiculation primarily along the anterior margin. The soft-tissue component of the tumor extends through the vertebral foramen, displacing and compressing the spinal cord (arrow). R = right side of patient. (3a) Axial T2-weighted gradient-echo MR image (repetition time msec/echo time msec = 644/27; 25° flip angle) demonstrates the high-signal-intensity tumor within the spinal canal. The tumor is seen displacing and compressing the spinal cord, which has lower signal intensity (arrow). The area of high signal intensity in the soft tissue represents posterior extension of the tumor not seen at CT (cf Fig 2). (3b) Sagittal T2-weighted spin-echo MR image (2,700/120) clearly delineates the cranial and caudal extent of the tumor (arrows).
