Due to the anatomical situation, intervertebral disc herniation usually results in compression of the anterior epidural space, with lateral or medial irritation of nerve root or cauda equina. Rare locations are an intra- or extraforaminal position or dislocation dorsally. Three patients with dorsal cauda equina compression caused by a sequestered herniated nucleus pulposus (HNP) are reported. The patients complained mainly of severe back pain. In two patients nondermatome-related leg pain was observed; one patient suffered additionally from incomplete cauda equina syndrome. In all cases magnetic resonance imaging and computed tomography diagnosed neoplastic tissue.
由于解剖学情况，椎间盘突出通常导致硬膜外前间隙受压，伴有神经根或马尾神经的外侧或内侧刺激。罕见的位置是椎间孔内或孔外位置或背侧脱位。报告了3例因游离性椎间盘突出症（HNP）导致马尾神经背侧受压的患者。患者主要诉说严重背痛。在2例患者中观察到与皮节无关的腿痛；1例患者还患有不完全马尾综合征。在所有病例中，磁共振成像和计算机断层扫描均诊断为肿瘤组织。
