FIG 2. Case 3: Cervical spine MR imaging performed 2 months after onset of neck pain, left upper distal extremity dysesthesia and paresis in patient 3. Symptom onset occurred 4 days after a vertebral disruption and chemotherapy. The patient's initial MR study showed findings similar to those in figure 1 (case 2).
A, Sagittal contrast-enhanced T1-weighted image shows linear anterior cord enhancement extending from C4 to C7.
B, Axial T1-weighted contrast-enhanced image at C5–C6 shows an enhancing signal occupying the anterior central portion of the cord. The distribution of this signal is symmetrical and involves mostly the gray matter, seeming to spare the peripheral white matter. There was no significant enhancement on the initial study.
