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。

Objective To investigate the CT and MRI manifestations of erector spinae muscle lesions and improve the diagnostic accuracy rate. Methods Twelve cases of patients with erector spinae muscle lesions were confirmed by clinical or pathological methords, their CT and MRI manifestations were observed retrospectively. Results There were four cases of epidermoid cyst, three cases of lipoma, two cases of diabetic myositis, one case of invasion by osteoid osteoma, one case of metastatic tumor, one case of hydatid disease. CT features of all these cases were characterized by low density. Epidermoid cyst had long T1 and long T2 signal, it’s signal in DWI was higher significantly;Lipoma had short T1 and long T2 signal; Diabetes myositis had enhancement similar to ring with enhanced scan;Hydatid disease appeared "polycystic" feature. Conclusion Erector spinae muscle lesions have special CT and MRI features. Combined with the clinical history, erector spinae muscle lesions can be judged effectively.
