摘要

早期髓鞘结构髓鞘化不足（HEMS）最近被定义为一种新的遗传性疾病，并伴有临床和磁共振成像特征。然而，还没有研究关注 HEMS 的弥散加权成像（DWI）结果。我们提出了一种 "绵羊征"，即内侧髓质层的 DWI 高强度和内囊后缘交替出现的高-低-高（HLH）强度条纹。我们认为，DWI 上出现的 "绵羊征 "与交替的 HLH 强度条纹相结合，可能是诊断 HEMS 的重要工具。

Diagnostic MR imaging features of hypomyelination of early myelinating structures: A case report.

Hypomyelination of early myelinating structures (HEMS) has recently been defined as a new genetic disorder accompanied by clinical and MR imaging characteristics. However, no studies have focused on diffusion-weighted imaging (DWI) findings of HEMS. We would like to propose a "sheep sign," which is formed by DWI hyperintensity in the medial medullary lamina along with alternating high-low-high (HLH) intensity stripes in the posterior limb of the internal capsule. We believe the presence of the "sheep sign" on DWI in combination with alternating HLH intensity stripes may be a valuable tool for diagnosing HEMS.

期刊介绍： NRJ - The Neuroradiology Journal (formerly Rivista di Neuroradiologia) is the official journal of the Italian Association of Neuroradiology and of the several Scientific Societies from all over the world. Founded in 1988 as Rivista di Neuroradiologia, of June 2006 evolved in NRJ - The Neuroradiology Journal. It is published bimonthly.
