CT和MRI对竖脊肌病变的诊断价值

目的探讨竖脊肌病变的CT和MRI影像学特征,以提高诊断符合率。方法回顾性分析12例经临床或病理证实的竖脊肌病变患者的CT及MRI影像学资料,总结其影像学特征。结果 12例患者中表皮样囊肿4例,脂肪瘤3例,糖尿病肌炎2例,骨样骨瘤侵犯1例,转移瘤1例,包虫病1例;CT表现均以低密度为主,表皮样囊肿为长T1长T2信号且弥散加权序列为显著高信号;脂肪瘤为短T1长T2信号;糖尿病肌炎增强扫描呈类环状强化;包虫病呈"多囊"改变。结论竖脊肌不同病变的CT和MRI表现具有不同特点,结合临床病史,可提高诊断符合率。

Value of CT and MRI in Diagnosis of Erector Spinae Muscle Lesions

Objective To investigate the CT and MRI manifestations of erector spinae muscle lesions and improve the dignstie accuracy rate.Methods Twelve cases of patients with erector spinae music lesions were confirmed by Clinical or pathological methords, their CT and MPI manifestations were observed retrospectively.Results There were four cases of epidermoid Cyst; three cases oflipoma, two cases of diabetic myositis, one case of invasion by osteoid ogeoma, one case of metastatic tumor, one case 0fhydatid disease, CT features of all these Casess were characterized by low density. Epidermoid cyst had long T1 and long T2 signal, it＇s signal iri DWI was higher ,significantly; Lipoma had short T1 and long T2 signal; Diabetes myositis had enhancement Similar to ring with enhanced scan; Hydadcl disease appeared ＂poyqystic＂ feature, Conclusion Erectorspinae muscle lesions have special CT and MRI features, Combined With the clinical history, erector spinae muscle lesions can be：judged：effectively.
