Title: The MRI findings of sporadic Creutzfeldt-Jakob disease
Abstract: Objective To study the MRI findings of sporadic Creutzfeldt-Jakob disease and its clinical relations. Methods MRI of 10 cases CJD patients were examined 2-12 months after the onset. 6 cases were diagnosed using cerebral biopsy, 8 cases received CSF analysis for 14-3-3 protein, 8 cases showed special changes of electroencephalogram, PrP gene of 9 cases were analyzed. Results Symmetric bilateral high signals were observed in caudate nucleus and Putamen in T 2-weighted imaging and Flair imaging in 5 cases, but the pallidum and thalamus were normal. No changes were found in T1-weighted imaging. 2 cases showed brain atrophy, 1 case showed mild lacunar infarction,and the other 2 were normal. Conclusions Abnormal signals in basal ganglia of 4 patients of 129Met/Met homozygote occurred after 2.5 months averagely, they survived for 10.5 months at average. 1 patient of 129 Met/Val heterozygote showed abnormal signals in basal ganglia after 12 months, and survived for 16 months. The mean duration of patient with abnormal signals in basal ganglia (12.2 months) is longer than those without changes in basal ganglia (5.5 months). Symmetric high signal in bilateral caudate nucleus and Putamen is an important imaging feature of sCJD. It might be served as a diagnostic index in some circumstances.
