Abstract

Mild malformation of cortical development with oligodendroglial hyperplasia (MOGHE) is a recently proposed epileptogenic entity that is difficult to detect on MRI. We present a case of MOGHE that was successfully detected on T1WI-chemical shift-selective saturation (CHESS) MRI. The clinical presentation, MRI including T1WI-CHESS, functional images, and pathology findings of a 14-year-old Japanese girl diagnosed with MOGHE are described. T1WI-CHESS revealed an abnormal high signal along the affected lesion, whereas the findings shown by the other MR sequences were less obvious; interictal fluorodeoxyglucose-positron emission tomography indicated slightly decreased accumulation in the lesion, and subtraction ictal single photon emission computed tomography co-registered to MRI showed an increased blood flow. Together these observations suggest that T1WI-CHESS may be a useful MR sequence for detecting the lesions in patients with MOGHE.

磁共振成像在 T1WI-CHESS 上检测到伴有少突胶质增生的轻度皮质发育畸形 (MOGHE)

皮质发育轻度畸形伴少突胶质增生（MOGHE）是最近提出的一种致痫实体，很难在核磁共振成像中检测出来。我们介绍了一例在 T1WI-化学位移选择饱和（CHESS）磁共振成像上成功检测出的 MOGHE。本文描述了一名确诊为 MOGHE 的 14 岁日本女孩的临床表现、磁共振成像（包括 T1WI-CHESS）、功能图像和病理结果。T1WI-CHESS显示受影响病灶沿线出现异常高信号，而其他磁共振序列显示的结果则不太明显；发作间期氟脱氧葡萄糖正电子发射断层扫描显示病灶内的积聚略有减少，与磁共振成像共同登记的减影发作期单光子发射计算机断层扫描显示血流增加。这些观察结果表明，T1WI-CHESS 可能是检测 MOGHE 患者病变的有用 MR 序列。
