UNASSIGNED: A 41-year-old woman was referred to our hospital from a nearby clinic because of transient left hemiparesis. Magnetic resonance (MR) imaging revealed mild stenosis of the bilateral MCAs. The patient then underwent MR imaging follow-ups once a year. MR imaging at the age of 53 showed a right M1 occlusion. Cerebral angiography revealed a right M1 occlusion and formation of a plexiform network consistent with the occlusion site, leading to the diagnosis of de novo T-MCA.
UNASSIGNED: This is the first case report describing possible de novo T-MCA formation. Although a detailed laboratory examination did not confirm the etiology, autoimmune disease was suspected to have precipitated this vascular lesion.
一名41岁的妇女因左半偏瘫而从附近的诊所转诊到我们医院。磁共振(MR)成像显示双侧MCA轻度狭窄。然后,患者每年接受一次MR成像随访。53岁时的MR成像显示右侧M1闭塞。脑血管造影显示右侧M1闭塞,并形成与闭塞部位一致的丛状网络,导致从头T-MCA的诊断。
■这是描述从头T-MCA可能形成的第一个病例报告。尽管详细的实验室检查没有确认病因,怀疑自身免疫性疾病导致了这种血管病变。
