The MRI of the brain shows a T2/FLAIR hyperintense, enhancing lesion in the left cerebellar hemisphere with a homogeneous enhancement pattern and mild perilesional edema. There is a T2/FLAIR hyperintense, enhancing lesion in the medulla at the level of the inferior medullary velum. Just inferior to this lesion, there is a solid-cystic lesion with an enhancing mural nodule. There is a similar lesion at the level of the C2 and D11 vertebrae.
