A 9-year-old boy presented with a subacute history of optic neuritis followed by brainstem involvement, with fever and a lymphocytic pleocytosis in the cerebrospinal fluid. Gadolinium-enhancing ring lesions were demonstrated in the white matter of the cerebrum, brain-stem and cerebellum on day 17 of the illness, all appearing simultaneously as part of a monophasic illness. A parietal lesion exerted mass effect. Needling and biopsy yielded no evidence of a pyogenic lesion, tumour or tuberculosis and showed vasculitis. There was insufficient material for myelin staining. Dexamethasone therapy lead to rapid improvement of the radiological lesions: MRI and CT on day 34 of the illness showed complete clearing of the lesions except for residual abnormality at the biopsy site.
一名9岁男孩出现视神经炎亚急性病史，随后累及脑干，伴有发热及脑脊液淋巴细胞增多。病程第17天，大脑、脑干和小脑白质出现钆增强环形病变，均同时出现，为单相病程的一部分。顶叶病变产生占位效应。穿刺活检未发现化脓性病变、肿瘤或结核证据，显示为血管炎。髓鞘染色材料不足。地塞米松治疗使放射学病变迅速改善：病程第34天的MRI和CT显示病变完全消退，活检部位除外仍有残余异常。
