To perform a systematic analysis and scoring of brain MRI white matter hyperintensities (WMH) in adult-onset Krabbe disease.
We retrospectively collected basic clinical data and the first available brain MRI from patients with confirmed Krabbe disease with first clinical manifestations beyond 10 years of age. Data were obtained from our reference center for lysosomal diseases (n = 6) and from contacted authors of published articles describing patients with adult-onset Krabbe disease (n = 15). T2-weighted fluid-attenuated inversion recovery images of each patient were analyzed and scored using a radiologic score of WMH in a single center.
The corticospinal tract was always affected by WMH (100% of patients), however, with some distinctions along the tract: the precentral gyrus (100%), corona radiata (95%), and posterior internal capsule (81%) were highly abnormal, whereas the mesencephalon (57%), pons (52%), and medulla oblongata (5%) were less affected. WMH were also frequently present in the posterior lateral periventricular white matter (95%), optic radiations (86%), postcentral gyrus (71%), medial lemniscus (62%), and corpus callosum, especially in the isthmus (71%), whereas the genu was always normal. A few patients did not have the classical MRI pattern but extensive hyperintensities (n = 3), or patchy distribution of hyperintensities mimicking an acquired etiology (n = 2), or very subtle hyperintensities of the corticospinal tract (n = 1).
We specified the main locations of WMH, which were observed in the earliest stages of the disease and were also present in patients with atypical MRI pattern, highlighting the importance of radiologic features to guide the diagnosis.
对成人发病型克拉伯病的脑 MRI 脑白质高信号(WMH)进行系统分析和评分。
我们回顾性收集了确诊的成人发病型克拉伯病患者的基本临床数据和首次发病 10 年后的脑 MRI。数据来自我们的溶酶体疾病参考中心(n=6)和已发表的描述成人发病型克拉伯病患者的文章的联系作者(n=15)。对每位患者的 T2 加权液体衰减反转恢复图像进行分析,并在一个中心使用 WMH 放射评分进行评分。
WMH 始终累及皮质脊髓束(100%的患者),但沿束存在一些差异:中央前回(100%)、放射冠(95%)和内囊后肢(81%)高度异常,而中脑(57%)、脑桥(52%)和延髓(5%)受影响较小。WMH 也常存在于侧脑室旁白质(95%)、视辐射(86%)、中央后回(71%)、内侧丘系(62%)和胼胝体,特别是在峡部(71%),而膝部总是正常的。少数患者没有典型的 MRI 模式,但有广泛的高信号(n=3),或高信号呈斑片状分布,类似于获得性病因(n=2),或皮质脊髓束的高信号非常细微(n=1)。
我们明确了 WMH 的主要部位,这些部位在疾病的早期阶段就已经存在,也存在于不典型 MRI 模式的患者中,这凸显了影像学特征对指导诊断的重要性。
