The prevalence of multiple sclerosis in the UK is among the highest in the world with prevalence in the north of Scotland presenting the peak of cases. Pathologically multiple sclerosis is regarded as multifocal areas of demyelination resulting in a spectrum of clinical manifestations, which pose diagnostic challenges. Dawson fingers are periventricular hyperintensities that that display high specificity for multiple sclerosis over all other demyelinating conditions. Intriguingly, they are also seen in cerebral small vessel diseasespectrum maladies.
In this case report we explore the presentation of Dawson finger hyperintensities in the primary diagnostic magnetic resonance imaging of a 26 year old white caucasian female with right-sided dysesthesia as the presenting complaint of relapsing remitting multiple sclerosis.
We further assess the sensitivity and specificity of Dawsons fingers upon multiple sclerosis diagnosis as well as their implications in differentiation between a family of demyelinating conditions with similar presentations. Lastly, we highlight the interplay between vascular and neuronal integrity in multiple sclerosis progression as highlighted by imaging and biochemical pathophysiology.
英国多发性硬化症的患病率位居世界前列,苏格兰北部的患病率最高。病理上,多发性硬化症被认为是脱髓鞘的多灶性区域,导致一系列临床表现,这给诊断带来了挑战。道森指是脑室周围高信号,在所有其他脱髓鞘疾病中,对多发性硬化症具有高度特异性。有趣的是,它们也见于脑小血管疾病谱病症中。
在本病例报告中,我们探讨了一名26岁白人女性复发性缓解型多发性硬化症的主要诊断磁共振成像中,以右侧感觉异常为首发症状的道森指高信号的表现。
我们进一步评估了道森指在多发性硬化症诊断中的敏感性和特异性,以及它们在鉴别一系列表现相似的脱髓鞘疾病中的意义。最后,我们强调了成像和生化病理生理学所突出的血管和神经元完整性在多发性硬化症进展中的相互作用。
