The authors report a rare case of an ovarian tumor metastasizing to the dura at L2-L3. It was seen at myelography to be intradural and by CT to be within the spinal canal. The latter exam eliminated a lipoma or a dermoid (both possible intradural or extramedullary-intradural tumor) from consideration.
作者报告了一例罕见的卵巢肿瘤转移至L2-L3硬脊膜的病例。脊髓造影显示该肿瘤位于硬膜内，CT检查显示其位于椎管内。后一项检查排除了脂肪瘤或皮样囊肿（两者均可能为硬膜内或髓外硬膜内肿瘤）的可能性。
