Abstract
The purpose of our study was to evaluate the remote effects on the cerebellum and cerebral cortex from subcortical hematoma without cortical structural abnormality. METHODS: Our study included 23 patients with hematoma, strictly confined either to the basal ganglia (n = 12) or thalamus (n = 11) without cortical abnormality on CT or MRI. Twenty psychiatric patients without structural abnormality on MRI were selected as control subjects. Technetium-ethyl cysteinate dimer brain SPECT was performed in patients and control subjects. Regional cerebral blood flow (rCBF) was visually and semiquantitatively assessed. Asymmetry index (AI) was determined using data from regions of interest at the basal ganglia, thalamus, cerebellum, frontal, parietal and temporal cortex to support the semiquantitative analysis. The criteria for defining hypoperfusion that reflected diaschisis was based on an AI > the mean + 2 s.d. of AI in control subjects. RESULTS: In the basal ganglia hematoma, rCBF was reduced significantly in the contralateral cerebellum (10/12), ipsilateral thalamus (12/12), ipsilateral frontal (6/12), parietal (12/12) and temporal cortex (10/12). As for thalamic hematoma, significantly reduced perfusion was seen in the contralateral cerebellum (10/11), ipsilateral basal ganglia (7/11), ipsilateral frontal (5/11), parietal (11/ 11) and temporal cortex (3/11). CONCLUSION: Crossed cerebellar diaschisis (CCD) and cortical diaschisis frequently were observed in patients with subcortical hematoma without cortical structural abnormality. This suggested that CCD can develop regardless of interruption of the corticopontocerebellar tract, which is the principal pathway of CCD.
