本文回顾性分析9例淋巴瘤中,椎体受累6例,2例有椎弓附件受累。脊柱信号异常形态4例呈弥漫性,2例呈斑片状信号异常,另2例呈轻度膨胀性改变,无1例呈压缩性改变。椎体周围及硬膜外间隙内软组织信号异常亦有3种,局灶梭形7个,在椎管内5例,其中2例环绕脊髓,2例于脊髓的后方,1例于脊髓前方,但均无椎弓附件的累及;弥漫长椭圆形1个;2例腰段椎管内呈弥漫性椎管铸型。淋巴瘤的信号8例T1加权图像呈等或低信号,T2加权为均匀等信号或不均匀略高、低信号改变,呈轻至中度增强;1例平扫时与前相同,但有明显增强。前者病理示血供欠丰富,后者示血供丰富。因此淋巴瘤的MRI表现有多种形态,其信号改变亦多种多样,但仍有一定特征。与转移性病灶相比,椎旁及硬膜外病灶倾向呈梭形改变,硬膜外病灶轴位显示明显大于骨质累及病灶,椎体骨质压缩性改变较少。与脊柱结核及硬膜外脓肿区别在于受累部位的椎间盘形态、信号显示正常。
In this retrospective analysis of 9 cases of lymphoma, 6 cases of vertebral involvement, 2 cases of pedicle attachment involvement. Spinal signal abnormalities were diffuse in 4 cases, patchy signal abnormalities in 2 cases, slight dilatation changes in 2 cases, and no compressive changes in 1 case. There were also 3 kinds of soft tissue signal abnormalities around the vertebral body and in the epidural space. There were 7 spindles in the spinal canal and 5 in the spinal canal. 2 of them surrounded the spinal cord, 2 were behind the spinal cord, and 1 was in front of the spinal cord. However, there was no involvement of the vertebral arch attachment; there was one diffuse long oval; two cases showed diffuse spinal cast in the lumbar spinal canal. The signal of lymphoma showed equal or low signal in 8 cases of T1-weighted images, and even or slightly uneven signals in T2-weighted, low-signal changes, showing mild to moderate enhancement; 1 case was the same as before but was clearly Enhanced. The former pathology shows a lack of blood supply, while the latter shows a rich blood supply. Therefore, there are many forms of MRI manifestations of lymphoma, and its signal changes are also varied, but still have certain characteristics. Compared with metastatic lesions, paravertebral and epidural lesions showed spindle-shaped changes, and the axial epidural lesions showed significantly more lesions than bone, and the changes in vertebral bone compression were less. The difference between spinal tuberculosis and epidural abscess lies in the normal shape of the intervertebral disc in the affected area.
