摘要
目的探讨脂肪纤维瘤病(lipofibromatosis,LPF)的CT或(和)MRI误诊原因,提高其术前诊断准确性。材料与方法回顾性分析经手术病理证实、术前CT或(和)MRI误诊的16例LPF临床及影像学资料。结果16例LPF均单发,临床上均表现为缓慢生长的无压痛性包块。CT、MRI上14(87.5%)例以脂肪密度或信号为主,15(93.8%)例纤维成分穿插于脂肪组织间,8(89%)例增强扫描后可见纤维成分强化。7例因其含丰富脂肪组织误诊为脂肪源性肿瘤,瘤体部分位于皮下并含有纤维成分误诊为神经纤维瘤病1例、纤维源性良性肿瘤1例、错构瘤1例,未行增强扫描误诊为脉管性肿瘤2例、良性病变4例。结论LPF的CT、MRI征象虽具有一定的特征性,但仍容易误诊为脂肪性肿瘤或纤维性肿瘤,发现脂肪密度或信号为主且穿插一些纤维成分浸润性生长的皮下肿瘤,应想到本病可能。
Objective:To study the CT/MRI misdiagnosis reason on lipofibromatosis(LPF)and improve the preoperative diagnostic accuracy.Materials and Methods:Retrospectively analyzed the surgical pathology,the clinical and imaging data of 16-misdiagnosis cases of LPF and their preoperative CT/MRI.Results:Sixteen cases of LPF were all single,clinically characterized as bag piece which was slow-growing without tenderness.On CT,MRI,there were 14(87.5%)cases,with thick density or the signal as priority.There were 15(93.8%)cases,with fiber inserted into adipose tissue.And 8(89%)cases,there was visible fiber reinforcement after enhanced scanning.And 7 cases,misdiagnosed as adipose tissue tumors because there was rich adipose tissue.Of which,1 case was misdiagnosed as neurofibromatosis located in the subcutaneous,1 case was misdiagnosed as fiber-sourced benign tumor,1 case was hamartoma,2 cases were misdiagnosed as a vascular tumor with no enhancement scanning,4 cases were benign lesions.Conclusions:Although the CT and MRI signs of LPF obtain certain characteristic,but it is easily misdiagnosed as thick-density tumors or fibrous tumor or subcutaneous tumor which is described with thick density or signal priority with some fiber composition invasive growth,should consider the disease.
