颌骨促结缔组织增生性纤维瘤的影像学分析
Radiographic analysis of desmoplastic fibroma of the jaw bones
摘要
Abstract
Objective To analyze the clinical manifestations and radiographic features of desmoplastic fibroma(DF).Methods The clinical and imaging findings of 17 patients with DF were retrospectively analyzed,including 11 male patients and 6 female patients,with the age ranged from 4-64 years old and a mean age of 20.27 years old.17 patients underwent CT examination(enhanced scan for 16 cases,non-enhanced CT for 1 case).5 patients underwent enhanced MR examination.Results The main clinical manifestations were painless mandibular mass and restricted mouth opening among 17 patients.All cases were in the mandibles,mainly located in the corner of the mandibles.CT images revealed expansile osteolytic lesions and partial compression bone destruction,central or eccentric growth,with soft tissue masses.All cases had"tree root-like"bone ridges.The lesions were divided into 2 types based on the different patterns of bone destruction:osteolytic type(n=12)and parosteal type(n=5).Lesions showed moderate/marked enhancement after contrast-enhanced scanning.All cases have no calcification and periosteal reaction.MR showed isointense or hypointense on T1 weighted images,hyperintense on T2 weighted images.The mean ADC value was 1.2×10-3 mm2/s.The time-signal intensity curve type of 3 cases was type Ⅰ,and 2 cases with type Ⅱ indicating benign tumor.Conclusion DF is invasive and prone to recurrence.By combining CT,MR and functional examinations,it is possible to reflect the tissue composition of the lesions,and provide important evidence for the accurate preoperative diagnosis.关键词
