[Abstract] Objective To study the CT/MRI misdiagnosis reason on lipofibromatosis (LPF) and improve the preoperative diagnostic accuracy. Materials andMethods 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.
