Neurology:见于视神经脊髓炎谱系疾病的皮质损害伴柔脑膜强化

2018-10-11 zyx整理 神经科病例撷英拾粹

27岁女性,表现为头痛伴双下肢无力和麻木2周。两年前,患者有难治性呃逆和呕吐,MRI上可见极后区病变

27岁女性,表现为头痛伴双下肢无力和麻木2周。两年前,患者有难治性呃逆和呕吐,MRI上可见极后区病变(图A-C)。感染性疾病筛查结果阴性。血清水通道蛋白-4-免疫球蛋白G阳性。最近的MRI可见邻近大脑镰的皮质损害伴柔脑膜强化(图D-F)。免疫球蛋白和大剂量甲基强的松龙治疗后症状和影像学明显好转(图G-I)。类似本例不常见,因为视神经脊髓炎谱系疾病罕见累及皮质和软脑膜。


(图:先前的T2WI,DWI和FLAIR图像[A-C]可见延髓高信号;最近的DWI和FLAIR可见局灶性皮质高信号[D-E]和柔脑膜强化[F];治疗后病灶改善[G-I])
