FIG1
MRI imaging six months after completion of craniospinal irradiation demonstrated improvement in LM disease of the cerebellum and spine, however, increased nodularity of enhancement at C1-C2 was seen (Figure 1).
Cervical Spine MRI showing rapid enlargement. Sagittal MRI of the cervical spine demonstrated substantial and rapid enlargement of the contrast enhancing lesion at the cervicomedullary junction.

FIG2
MRI of the cervical spine demonstrated substantial and rapid enlargement of the contrast enhancing lesion at the cervicomedullary junction, to a craniocaudal dimension of 22 mm (Figure 2).
