【摘要】：目的探讨胸腰段椎管内肿瘤的临床特征和磁共振成像(MRI)的诊断价值分析。方法回顾性分析2014年1月至2016年2月27例经手术和病理确诊为胸腰段椎管内肿瘤患者的临床资料和MRI影像学资料。结果首发症状包括腰背部胀痛、下肢麻木无力、大小便功能障碍、感觉异常或痛觉减退等,症状多进行性加重,有由上至下扩散的特点。27例患者经病理证实髓内肿瘤5例,硬膜外肿瘤3例,髓外硬膜下肿瘤19例,MRI定位准确26例(96.30%),定性准确21例(77.78%)。MRI扫描髓内肿瘤多呈等T1、等长T2异常信号,髓外硬膜下肿瘤多呈等低T1信号、等高T2信号,增强扫描后多显示环状或不均匀强化。硬膜外肿瘤包括血管瘤和结核性肉芽肿,血管瘤呈等T1信号高T2信号,结核性肉芽肿呈略低T1信号、等长T2信号。结论胸腰段椎管内肿瘤早期临床特征不典型,MRI诊断定位准确率和定性准确率均较高,是椎管内肿瘤诊断的有效方法。
[Abstract]:Objective to investigate the clinical features and MRI of thoracolumbar spinal canal tumors. Methods from January 2014 to February 27th 2016, clinical data and MRI imaging data of patients with thoracolumbar spinal canal tumors confirmed by operation and pathology were retrospectively analyzed. Symptoms include pain in the lower back. Numbness and weakness of lower extremity, dysfunction of defecation and urination, abnormal sensation or hypoalgesia, etc., the symptoms of which were more progressive and aggravated. There were 27 cases of intramedullary tumors confirmed by pathology with the characteristic of spreading from top to bottom. 5 cases of intramedullary tumors were confirmed by pathology. There were 3 cases of epidural tumor, 19 cases of subdural extramedullary tumor, 26 cases of accurate location of MRI, 21 cases of qualitative accuracy, 77.78%. MRI scan of intramedullary tumors showed iso-T1. Isochronal T2 abnormal signal intensity, submedullary subdural tumors show iso-low T1 signal intensity, iso-high T2 signal intensity, enhanced scan more ring or uneven enhancement. Epidural tumors include hemangioma and tuberculous granuloma. Hemangioma showed high T 1 signal intensity while tuberculous granuloma showed low T 1 signal intensity and equal long T 2 signal intensity. Conclusion the early clinical features of thoracolumbar spinal canal tumors are not typical. MRI is an effective method for the diagnosis of intraspinal tumors.

【正文快照】： 椎管内肿瘤是指脊髓本身、脊髓邻近组织以及椎管内发生的原发性或继发性肿瘤[1]。椎管内肿瘤早期临床特征具有多样性,且多不典型,例如腰背部疼痛、肩颈酸痛、卧位根性疼痛等,易被漏诊、误诊为临床多发病[2]。椎管内肿瘤的生长部位包括脊髓内、脊髓外硬膜内、硬外膜三类,因此在
