骨韧带样纤维瘤的影像学表现及病理对照

Imaging Features ang Pathological Findings of Desmoid Like Fibroma

目的分析骨韧带样纤维瘤的影像学表现,并与病理表现对照。方法选取黑龙江省哈尔滨市第四医院2015年2月—2017年2月收治的骨韧带样纤维瘤患者20例,分析其影像学表现并与病理对照。结果 X线检查溶骨性破坏55.0%为中心性,45.0%为偏心性;CT检查87.5%为溶骨性破坏,软组织肿胀有较清晰的界限;MRI检查显示T1WI病变区域信号强度比对于周边肌肉均为略低信号或等信号;术前误诊率为90.0%,2例与术后病理对照结果一致。结论影像学检查误诊率高,需联合诊断,并结合临床症状与病理表现。

Objective To analyze the imaging findings of bone ligamentous fibroma and compare it with pathological manifestations.Methods Twenty patients with bone ligamentous fibroma treated from February 2015 to February 2017 in Harbin City,Heilongjiang Province were selected and analyzed for their imaging findings.Results X-ray examination of osteolytic destruction of 55.0%as the center,45.0%for eccentricity;CT examination 87.5%for osteolytic destruction,soft tissue swelling have a clearer boundaries;MRI examination showed T1 WI lesion area signal intensity ratio for peripheral muscle For the slightly lower signal or other signals;preoperative misdiagnosis rate was 90.0%,2 cases and postoperative pathological control results consistent.Conclusion Misdiagnosis rate of imaging examination is high,need to be combined with diagnosis,combined with clinical symptoms and pathological manifestations.
