摘　　要：目的:分析良性对称性脂肪增多症(benign symmetric lipomatosis,BSL)的CT影像特征,评价CT对BSL的诊断价值。方法:回顾分析9例良性对称性脂肪增多症的CT影像表现。9例平扫,其中5例同时行增强扫描。结果:所有患者CT表现为枕部、颈部、上背部等不同部位皮下或肌间隙内脂肪沉积增厚,病灶无包膜,边界不清,左右对称,蓄积脂肪内无钙化,结论:CT能清楚表现BSL病灶大小及范围,在诊断及术前定量、定位诊断方面具有重要价值。Objective：To analyse CT characteristic of the benign symmetric lipomatosis,and to evaluate the value of CT in diagnosis of the benign symmetric lipomatosis.Methods：CT findings of 9 cases with benign symmetric lipomatosis in the head and neck region were analyzed retrospectively.9 cases were performed plain CT scan and enhanced CT scan was performed on 5 of them at the same time.Results：Accumulation of non-encapsulated fat tissue in the head and neck region was depicted on CT images in the neck of all patients.The fat deposits were ill defined and symmetrical,no calcification within the lipomatous deposits.The non-encapsulated fat tissue deposited in subcutaneous and between muscles of the occipital and neck and upper trunk regions.Conclusion：CT seems to be the most reliable method of detecting deep lipomatous masses.CT can clearly demonstrate the distribution of fat in the occipital and neck and upper trunk regions,and has a great value in quantitative and locating diagnosis before operation.
