title: Acute cerebellitis presenting as tumor. Report of two cases.
abstract: A pseudotumoral presentation of acute cerebellitis is rare. The authors report two cases of children with hemicerebellar involvement, neither case being postinfectious nor vaccination related. One patient underwent biopsy sampling revealing marked parenchymal and leptomeningeal inflammation, and in the other, near-complete resolution of neuroimaging abnormalities was demonstrated. The literature is reviewed and therapy considerations are emphasized.
