title: MR evaluation of crossed and uncrossed cerebral-cerebellar diaschisis.
abstract: In three patients with infantile hemiplegia syndrome, MR imaging done later in life showed significant volume loss in the cerebellar hemisphere contralateral to the side of the affected cerebrum in two and ipsilateral in one. By comparison, the cerebellar volume loss seemed to correlate with the degree of volume loss in the contralateral cerebral hemispheres in two patients. These observations provide morphological evidence of the phenomenon of crossed and uncrossed/ipsilateral cerebral cerebellar diaschisis (CCD and ICD). Functional neuroimaging studies in support of the concept of CCD and ICD have been critically reviewed in the light of the morphological changes demonstrated in the cases cited herein.
