We report a rare case of intradural lumbar disc protrusion describing a specific myelographic appearance that may help in preoperative diagnosis. Most of these patients present with acute sciatica and neurologic deficit. Preoperative awareness and diagnosis is of importance because the extruded disc protrusion lies intrathecally and must be specifically looked for and removed from its intradural position.
我们报告了一例罕见的硬膜内腰椎间盘突出症，描述了一种有助于术前诊断的特殊脊髓造影表现。这些患者大多表现为急性坐骨神经痛和神经功能缺损。术前的认知和诊断很重要，因为突出的椎间盘位于鞘内，必须专门查找并从其硬膜内位置摘除。
