A 50-year-old man with a family history of stroke and depression slowly developed brain lesions. Magnetic resonance imaging revealed hyperintense lesions in the diffuse white matter, external capsules, and temporal poles on T2-weighted imaging. A heterozygous mutation c.3879C>G in exon 24 of the NOTCH3 gene (p.Cys1293Trp) was detected, confirming a diagnosis of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). Exon 24 mutations are rather rare and this represents the first Japanese case of CADASIL.
一名有中风和抑郁症家族史的50岁男性逐渐出现脑部病变。磁共振成像显示,在T2加权成像上,弥漫性白质、外囊和颞极有高信号病变。检测到NOTCH3基因第24外显子存在杂合突变c.3879C>G(p.Cys1293Trp),确诊为伴有皮质下梗死和白质脑病的大脑常染色体显性动脉病(CADASIL)。第24外显子突变相当罕见,这是日本首例CADASIL病例。
