We report an anatomical-based association between conus medullaris pial arteriovenous shunt that drain caudally towards the lumbosacral area with very delayed onset of an acquired lumbar epidural shunt, draining secondarily towards intradural veins and responsible for a venous congestive myelopathy with identical clinical symptoms. These patients require close clinical and imaging follow-ups in order to propose adequate treatments before onset of irreversible neurological deficits. MRA should include the lumbo-sacral area in its field of view.

原发性脊髓圆锥动静脉分流术和继发性腰骶硬膜外动静脉瘘：一个畸形可以隐藏另一个

我们报告了脊髓圆锥软脑膜动静脉分流向腰骶部尾部引流与获得性腰椎硬膜外分流发生非常延迟、继发向硬膜内静脉引流并导致具有相同临床症状的静脉充血性脊髓病之间的基于解剖学的关联。这些患者需要密切的临床和影像学随访，以便在出现不可逆转的神经功能缺损之前提出适当的治疗方案。MRA 应将腰骶区域包括在其视野中。
