T2- and enhanced T1-weighted sagittal images of the cervical spine. In 2004, there was high T2 signal in the cord at the cervico-medullary junction and C4-5 (a, arrows) and at C7-T1 (b). The lesion at C7-T1 enhanced (c). In 2005, the T2 signal abnormalities significantly improved (d,e) and enhancement resolved (f). In 2006, there was recurrence of high T2 signal in the spinal cord especially at C2 (g,h) and at C6-7 (g), without enhancement (i).

In September 2004, a cervical MRI revealed abnormal signal extending from the medulla to the thoracic region with enhancement at C7-T1 (Fig.1, panels a-c; Fig. 2 panels a,b). In May 2005, enhancement resolved, and there was significant improvement in cord signal (Fig.1, panels d-f; Fig. 2, panels c,d). C2 to T1 (Fig. 1, panels g-i; Fig. 2, panels e,f). CSF examination was normal.
