A 52-year-old patient with mosaic Down's syndrome exhibiting clinical features of early dementia who underwent high resolution SPECT neuroimaging is reported. While a CT scan of the brain showed no abnormality, cranial SPECT confirmed the presence of marked cortical blood flow deficits.
报告了一名52岁患有嵌合型唐氏综合征的患者，其表现出早期痴呆的临床特征，并接受了高分辨率单光子发射计算机断层扫描（SPECT）神经成像检查。虽然脑部CT扫描未显示异常，但头颅SPECT证实存在明显的皮质血流灌注不足。
