Abstract:
UNASSIGNED: Intervertebral disc herniation, defined as the protrusion or extrusion of the disc mass outside the disc space, is common and easy to diagnose on conventional Magnetic Resonance imaging (MRI) or Computed Tomography (CT) scans. However, the sequestrated disc fragments are challenging to detect, and intervertebral disc mass displacement into the dural sac, which can lead to serious neurological problems such as Cauda equina syndrome (CES). The sequestrated disc fragments do not have specific clinical or radiological characteristics that can differentiate an atypical disc mass from a tumor, making the diagnosis difficult preoperatively. Herein, we describe the use of Sampling Perfection with Application Optimized Contrast using different flip angle Evolution in Magnetic Resonance Imaging (3D SPACE MRI) in the diagnosis of the intervertebral disc fragment that mimicked a tumor.
UNASSIGNED: In this study, we report two cases of sequestered lumbar disc herniation. The first case was a 37-year-old patient with a 2-year history of intermittent left lower limb pain that aggravates with exercise and is relieved at rest, while the second case was a 42-year-old patient with a history of 40 days of numbness and pain in the left lower limb.
UNASSIGNED: 3D SPACE MRI is a beneficial diagnostic imaging tool for discriminating between disc mass that mimics a tumor and a tumor before surgery. If the disc fragment mimicking a tumor can be identified before the operation, open surgical treatment won\'t be necessary for all patients.
摘要:
■椎间盘突出症,定义为椎间盘块在椎间盘空间外的突出或挤压,在常规磁共振成像(MRI)或计算机断层扫描(CT)扫描中很常见且易于诊断。然而,被隔离的椎间盘碎片很难检测,椎间盘肿块移位进入硬膜囊,这可能导致严重的神经系统问题,如马尾综合症(CES)。隔离的椎间盘碎片没有特定的临床或放射学特征,可以区分非典型椎间盘肿块和肿瘤。使术前诊断困难。在这里,我们描述了在磁共振成像(3DSPACEMRI)中使用不同翻转角演变的应用优化对比剂采样完美在模拟肿瘤的椎间盘碎片诊断中的应用。
■在这项研究中,我们报告2例隔离型腰椎间盘突出症。首例为37岁患者,有2年间歇性左下肢疼痛病史,随运动加重,休息时缓解,而第二例是一名42岁的患者,有40天的左侧下肢麻木和疼痛的病史。
■3DSPACEMRI是一种有益的诊断成像工具,用于区分模拟肿瘤的椎间盘肿块和手术前的肿瘤。如果在手术前可以识别出模仿肿瘤的椎间盘碎片,并不是所有患者都必须进行开腹手术治疗。
