A Case of Acute Cerebellitis / 대한소아신경학회지

Acute 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. The clinical presentations are abnormal eye movement, truncal ataxia, dysarthria, nausea, headache, tremor, convulsion and altered mental status. Many patients with cerebellitis are supposed to have normal MRI findings. But hyperintense signals of cerebellar gray matter in T2-weighted sequences of MRI can be used as a strong indication of acute cerebellitis. We report here a case of acute cerebellitis with abnormal MRI findings in 7 years old patient with diplopia and tremor.
