The patient primarily presented with dizziness accompanied by vertigo and a positive Romberg＇s sign. Skull magnetic resonance images showed lacunar infarction in bilateral temporal lobes, bilateral basal ganglias, periventricular white matter and semioval center, and ischemic focus accompanied by white matter degeneration, exhibiting senile morphological brain changes. No abnormalities were observed by skull magnetic resonance angiography. Gene detection further confirmed that there was Arg607Cys heterozygous mutation in exon 11 of the Notch3gene. No other mutations in exons were detected.展开更多
