CT,MRI misdiagnosis analysis of fat fibromatosis

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.
