【摘要】：目的探讨MRI对椎管内原发性淋巴瘤诊断和鉴别诊断的价值。方法搜集经手术或穿刺病理证实的椎管内原发性淋巴瘤19例,行全身骨显像检查均未见确切骨转移征象,行骨髓穿刺检查均呈阴性,结合临床特征回顾性分析其MRI表现。结果 19例MRI表现为椎管内硬膜外软组织肿块,矢状面呈长条形,横断面呈半月形,14例向椎管外呈钻孔样生长。12例合并相邻椎骨骨质破坏,多位于椎弓附件区,其中8例软组织肿块范围大于骨质破坏范围,5例伴有压缩性骨折。软组织肿块信号均匀,边界清楚,以T1WI等信号、T2WI稍高信号为主,脂肪抑制序列呈高信号,增强后呈轻中度均匀或不均匀强化。骨质破坏为斑片状T1WI低信号,T2WI低或高信号,脂肪抑制序列呈高信号,结论椎管内原发性淋巴瘤MRI表现有一定的特征,把握这些特征有助于做出正确的诊断和鉴别诊断。
[Abstract]:Objective to investigate the value of MRI in the diagnosis and differential diagnosis of intraspinal primary lymphoma. Methods 19 cases of primary lymphoma in spinal canal confirmed by surgery or puncture pathology were collected. No exact bone metastasis was found in all bone scintigraphy, and the bone marrow biopsy was negative. The results of MRI were retrospectively analyzed with clinical features. Results 19 MRI showed a soft tissue mass in the spinal canal. The sagittal face was long striped, and the cross section was half moon. 14 cases were bored out of the spinal canal,.12 combined with adjacent vertebral bone destruction, and most of them were in the appendage area of the vertebral arch. Among them, 8 cases of soft tissue masses were larger than bone destruction and 5 cases were accompanied by compression fracture. Soft tissue mass signal was uniform. The boundary is clear, with the signal of T1WI and so on, T2WI slightly high signal is the main signal, the fat suppression sequence is high signal, after enhancement, it is mild to moderate or uneven intensification. The bone destruction is flaky T1WI low signal, T2WI low or high signal, the fat suppression sequence is high signal. Conclusion the MRI manifestations of the primary lymphoma in the spinal canal have certain characteristics, grasp these characteristics. It is helpful to make the correct diagnosis and differential diagnosis.
