■Schmorl的淋巴结是髓核通过软骨和骨终板进入相邻椎骨的突出物。Schmorl的淋巴结极为常见,通常被视为放射线影像上的偶然发现。在验尸研究中,据估计,超过70%的人口有Schmorl的节点。很少,然而,Schmorl的节点可能是急性背痛的原因,甚至更少,神经根病.
■在目前的情况下,一名老年男性出现急性下腰痛和神经根病。MRI显示一个大的L3椎体下终板Schmorl淋巴结,向后延伸穿过椎体皮质并进入上方的腹侧硬膜外腔。这导致右侧L2-L3关节下隐窝严重消失,以及右侧L3-L4神经孔,撞击右侧L3神经根.周围皮质水肿和MRI增强进一步提示急性Schmorl淋巴结。
■虽然罕见,Schmorl的节点可能是急性背痛的原因,甚至更不常见,神经根病.诊断Schmorl淋巴结的影像学选择是MRI,因为它具有更大的检测水肿的能力。新生血管形成,在这种情况下,挤压圆盘材料。在无症状和有症状的病例中,Schmorl淋巴结的主要治疗方法是保守治疗。在由隧道Schmorl淋巴结压迫引起的持续性神经根病的情况下,手术切除椎间盘材料是成功的。
UNASSIGNED: Schmorl\'s nodes are herniations of nucleus pulposus through the cartilaginous and bony endplate into the adjacent vertebra. Schmorl\'s nodes are extremely common and are typically seen as incidental findings on radiographic imaging. In postmortem studies, it has been estimated that greater than 70% of the population has Schmorl\'s nodes. Rarely, however, Schmorl\'s nodes can be a cause of acute back pain and, even less often, radiculopathy.
UNASSIGNED: In the present
case, an elderly male presented with an acute onset of lower back pain and radiculopathy. MRI demonstrated a large L3 vertebral body inferior endplate Schmorl\'s node with posterior extension through the vertebral body cortex and into the ventral epidural space superiorly. This resulted in severe effacement of the right L2-L3 subarticular recess, as well as the right L3-L4 neural foramen, impinging on the right L3 nerve root. Surrounding cortical edema and enhancement on MRI further suggested an acute Schmorl\'s node.
UNASSIGNED: Although rare, Schmorl\'s nodes can be a cause of acute back pain and, even less commonly, radiculopathy. The imaging modality of choice for the diagnosis of a Schmorl\'s node is MRI as it has a greater capability to detect edema, neovascularization, and in this
case, extruded disc material. In both asymptomatic and symptomatic cases, the mainstay of treatment for Schmorl\'s nodes is conservative therapy. Surgical removal of disc material has been successful in cases of persistent radiculopathy from compression by a tunneling Schmorl\'s node.
