A 21 year old woman with subacute onset of moderate left hemiparesis showed on CT scanning a left parietal ring shaped enhancing lesion indicative of tumour or abscess, while MRI revealed bilateral white matter lesions highly suggestive of MS. In none of the few similar cases reported was MRI available and most patients underwent biopsy or operation. The few reports of a CT-ring sign in MS are reviewed and the value of MRI in avoiding operation is stressed.
一名21岁女性，亚急性起病，出现中度左侧偏瘫，CT扫描显示左侧顶叶有环形强化病灶，提示肿瘤或脓肿，而MRI显示双侧白质病变，高度提示多发性硬化症（MS）。在已报道的少数几例类似病例中，均未进行MRI检查，大多数患者接受了活检或手术。本文回顾了少数几例MS患者出现CT环形征的报道，并强调了MRI在避免手术方面的价值。
