Abstract

Background: Leptomeningeal enhancement, visible on MRI, can indicate a variety of diseases, both neoplastic and non-neoplastic.

Objective: This comprehensive pictorial review aims to equip radiologists and trainees with a thorough understanding of the diverse imaging presentations of leptomeningeal disease.

Methods: Drawing from a retrospective analysis of MRI scans conducted between 1 January 2008 and 30 September 2022, at two tertiary teaching hospitals in Singapore, this review covers a wide range of conditions. Case Collection: The main neoplastic conditions discussed include leptomeningeal carcinomatosis, myelomatosis, schwannoma, CNS lymphoma, and pineal region tumors. Additionally, the review addresses non-neoplastic enhancements such as meningoencephalitis, intracranial hypotension, cerebral ischemia/infarction, epidural lipomatosis, syringomyelia, Sturge-Weber syndrome, and subarachnoid hemorrhage.

Conclusion: By highlighting the imaging features and patterns associated with these conditions, the review underscores the critical role of accurate diagnosis and timely management in improving patient outcomes. Enhanced understanding of these conditions can significantly improve patient outcomes through timely and effective therapeutic interventions.

轻脑膜肿块或假面舞会：一系列伴有轻脑膜增强的疾病及其模拟。

背景：MRI上可见的轻脑膜增强可提示多种疾病，包括肿瘤和非肿瘤。目的：这篇全面的图片综述旨在使放射科医生和培训生对脑膜疾病的各种影像学表现有全面的了解。方法：从2008年1月1日至2022年9月30日在新加坡两所三级教学医院进行的MRI扫描的回顾性分析中，本综述涵盖了广泛的条件。病例收集：主要讨论的肿瘤疾病包括脑膜轻脑癌、骨髓瘤、神经鞘瘤、中枢神经系统淋巴瘤和松果体区肿瘤。此外，该综述还讨论了非肿瘤性增强，如脑膜脑炎、颅内低血压、脑缺血/梗死、硬膜外脂肪瘤病、脊髓空洞、斯特奇-韦伯综合征和蛛网膜下腔出血。结论：通过强调与这些疾病相关的影像学特征和模式，本文强调了准确诊断和及时治疗对改善患者预后的关键作用。加强对这些疾病的了解可以通过及时有效的治疗干预显著改善患者的预后。
