[Crossed "cerebral" diaschisis? Seven cases with unilateral cerebellar vascular lesion which showed decreased perfusion in the contralateral cerebral cortex].
In 7 cases with unilateral cerebellar vascular lesion, decreased perfusion was observed in the contralateral cerebral cortex by single photon emission computed tomography (SPECT) with I-123 labeled N-isopropyl-p-iodoamphetamine (IMP). These cases had symptoms due to cerebellar lesions but did not show any cerebral cortical symptoms. Reduction of cerebral cortical perfusion appeared on more than 25 days after the onset of CVA, did not correlate with morphological changes by cranial X-ray computed tomography and digital subtraction angiography in acute phase, and was persistent or irreversible later. We made a guess this phenomenon was due to the remote neuronal effect through cerebellothalamic projection.
