Abstract:
After supratentorial infarction. Crossed cerebellar diaschisis has been described. And there was also a report of crossed cerebral diaschisis in cerebellar infarction as a rare phenomenon. We analyzed 36 patients with cerebellar ischemic stroke by using 99mTc-HMPAO single photon emission computed tomography (SPECT). All the patients showed depression of perfusion on the side of cerebellum. Among them, contralateral cerebral reduced uptake was also observed in 8 patients (22%). Uhich showed marked reduction in frontoparietal junction area (especially premotor area). SPECTs were done relatively earlier in those patients(diaschisis +: N=8) than the others(diaschisis -; N=28). They comprised 6 patients of posterior inferior cerebellar arterial territory infarction. One patient in anterior inferior cerebellar artery and one in superior cerebellar artery. Six patients were followed-up by second SPECT images. Most of the depressed perfusions (primary lesions and diaschisis areas) were improved with functional recovery at the follow-up SPECT images.
