We describe 2 cases of a spinal cord lesion with imaging features closely resembling those described in supratentorial multinodular and vacuolating neuronal tumor (MVNT) or infratentorial multinodular and vacuolating posterior fossa lesions of unknown significance. Multiple well-delineated nonenhancing T2-hyperintense intramedullary cystic ovoid nodules were visualized within the white matter of the spinal cord, including some immediately abutting the gray matter. No alterations in signal intensity or morphology were detected in a follow-up. Moreover, no relevant clinical symptoms attributable to the lesions were present. We describe these lesions as presumed MVNT, and we therefore use the term MVNT-like spinal cord lesions.

我们描述了 2 例脊髓病变，其影像学特征与幕上多结节性空泡性神经元肿瘤 (MVNT) 或幕下多结节性空泡性后颅窝病变（意义不明）非常相似。在脊髓白质内可见多个轮廓清晰的非增强 T2 高信号髓内囊性卵圆形结节，包括一些直接邻接灰质的结节。在后续行动中没有检测到信号强度或形态的改变。此外，不存在与病变相关的临床症状。我们将这些病变描述为假定的 MVNT，因此我们使用术语 MVNT 样脊髓病变。
