title: Magnetic resonance imaging findings in acute cerebellitis.
abstract: Cerebellitis, also known as acute cerebellar ataxia, is an inflammatory syndrome of cerebellar dysfunction that may reflect an infectious, post-infectious, or post-vaccination disorder. We present serial magnetic resonance imaging (MRI) findings in a partially reversible, idiopathic cerebellitis. Bilateral cerebellar parenchymal abnormalities were noted, including hyperintensities on T2-weighted images and cerebellar swelling. After contrast administration, the cerebellum showed abnormal bilateral enhancement. The authors state this represents the first report of abnormal contrast enhancement in this condition. The MRI lesions most likely reflect the reversible, inflammatory nature of the syndrome.
