摘　　要：目的总结腰（骶）背部皮下滑囊炎的出现率和MRI表现，探讨其发病机制和鉴别诊断。方法从1848例腰（骶）椎MRI资料中挑选拟诊为腰（骶）背部皮下滑囊炎者159例进行回顾性分析。54例经手术、穿刺或随访证实。结果54例（确诊者）病变位于腰（骶）段背侧中部浅筋膜层，矢状位和横轴位为条带状、长梭形或分房状囊性病变，范围不一。51例病变呈长T1、长T2水样信号，3例病变呈血性积液信号。48例伴腰（骶）部其他病变，6例为单纯性病变。105例（失随访者）病变均符合腰（骶）背部皮下滑囊炎MRI特征。结论MRI是检出和诊断腰（骶）背部皮下滑囊炎的最佳影像学方法。Objective To summarize the incidence and MRI manifestations of subcutaneous bursitis in low hack, and to discuss its etiology and differentiating diagnosis . Methods 159 cases with prediagnosed subcutaneous bursitis from 1848 cases examined by MRI were respectively analyzed. Of them,54 cases were proved by surgery and pathology or follow-up. Results The lesions in 54 cases proved by clinic were seen in the middle line of superficial fascia in low back. The lesions were shuttle shape or multi cystic on axial and sagittal MR images. MRI showed fluid-signal lesions（n= 51） with low signal intensity on T1WI and high signal intensity on T2 WI, and hemorrhage--signal lesions（ n= 3） with high or middle signal intensity on T1 WI and high signal intensity on T2 WI. 48 cases accompanied with other lumbosacral lesions. The other 105 cases without followed--up also had MRI manifestations of subcutaneous bursitis . Conclusion MRI is a most important method to detect and diagnose subcutaneous bursitis in low back.
