摘要

认识进行性多灶性脑白质病的MRI特征对早期诊断至关重要。本报告描述了已知年龄最大的病例，一名83岁男子患有快速进展性痴呆和艾滋病毒相关的经典PML。脑MRI显示标志性的发现，包括顶枕区不对称、连续、无增强的皮质下病变和小脑白质的“虾征”。这些特征性的影像学模式，在适当的临床背景下，是PML早期识别的线索。

MRI Shrimp Sign and Parietooccipital Lesion in Progressive Multifocal Leukoencephalopathy.

Recognizing the MRI characteristics of progressive multifocal leukoencephalopathy is essential for early diagnosis. This report describes the oldest known case of an 83-year-old man with rapidly progressive dementia and HIV-associated classic PML. Brain MRI revealed hallmark findings, including asymmetric, continuous, non-enhancing subcortical lesions in the parietooccipital regions and the "shrimp sign" in the cerebellar white matter. These characteristic imaging patterns, in the appropriate clinical context, are clues for the early identification of PML.

期刊介绍： Official publication of the Society for Research on the Cerebellum devoted to genetics of cerebellar ataxias, role of cerebellum in motor control and cognitive function, and amid an ageing population, diseases associated with cerebellar dysfunction. The Cerebellum is a central source for the latest developments in fundamental neurosciences including molecular and cellular biology; behavioural neurosciences and neurochemistry; genetics; fundamental and clinical neurophysiology; neurology and neuropathology; cognition and neuroimaging. The Cerebellum benefits neuroscientists in molecular and cellular biology; neurophysiologists; researchers in neurotransmission; neurologists; radiologists; paediatricians; neuropsychologists; students of neurology and psychiatry and others.
