Cerebral high grade glioma with crossed cerebellar metastases. A report of three cases.

We describe three patients with high grade supratentorial gliomas who were operated and later presented with cerebellar mass lesions on the opposite side. Supratentorial infarct with crossed cerebellar atrophy is a well-known entity called crossed cerebellar diaschisis. We hypothesize that supratentorial high grade tumours might also spread to the opposite cerebellum through crossed cerebrocerebellar fiber tracts similar to crossed cerebellar diaschisis.
