MRI findings specific for lesions of the optic nerve are reported in the present paper for the first time: a dilated subarachnoidal space during the acute phase and scars in the neural tissue several months later. For imaging, the authors used special pulse sequences and surface coils. Twenty of 37 patients presenting with these symptoms were suffering from retrobulbar neuritis. In at least 12 (60%) of them the neuritis was associated with multiple sclerosis. Patients with tumors of the sella region usually have bilateral edema in the subarachnoidal spaces of both nerves. The edema is always located distal to the nerve lesion. The subarachnoidal edema is only of limited significance as a sign of optic neuritis. On the other hand, the authors failed to find a single case of neuritis without such edema.
本文首次报道了视神经病变的特异性磁共振成像（MRI）表现：急性期蛛网膜下腔扩张，数月后神经组织出现瘢痕。为进行成像，作者使用了特殊脉冲序列和表面线圈。37例出现这些症状的患者中，20例患有球后视神经炎。其中至少12例（60%）的神经炎与多发性硬化相关。蝶鞍区肿瘤患者通常双侧神经的蛛网膜下腔出现水肿。水肿总是位于神经病变的远端。蛛网膜下腔水肿作为视神经炎的征象，其意义有限。另一方面，作者未发现一例没有这种水肿的神经炎病例。
