Case Report - Crossed Cerebral - Cerebellar Diaschisis : MRI Evaluation

MRI, done later in life, in two patients with infantile hemiplegia syndrome showed significant volume loss in the cerebellar hemisphere contralateral to the side of the affected cerebrum. The cerebellar volume loss seemed to correlate with the degree of volume loss in the contralateral cerebral hemisphere. These observations provide morphological evidence of the phenomenon of crossed cerebral-cerebellar diaschisis (CCD). Functional neuroimaging studies in support of the concept of CCD has been critically reviewed.
